     Referring to  FIG. 3 , the weight member  148  can comprise one or more splines  168  located on and protruding from the side wall  164  of the weight member  148 . When the weight member  148  is positioned within the cavity  128  of the club head  100 , the splines  168  are configured to abut the side surface  136  of the cavity  128  and the weight member  148 . This abutment generates a press fit of the weight member  148  within the cavity  128 . 
     In the illustrated embodiment, the side wall  164  has eight splines  168 , including two splines  168  on each surface of the side wall  164 . In other embodiments, the side wall  164  of the weight member  148  can comprise any number of splines  168  including, one, two, three, four, five, six, seven, eight, or more splines  168 . In the illustrated embodiment, the splines  168  are evenly spaced along the side wall  164 . In other embodiments, the splines  168  can be unevenly spaced or can comprise any spacing. 
     The one or more splines  168  comprise a length measured from an end of the spline  168  nearest to the upper surface  160  of the weight member  148 , to an opposing end of the spline  168  nearest the lower surface of the weight member  148 . In the illustrated embodiment, the length of the splines  168  is substantially the same as the height of the side wall  164 . In other embodiments, the length of the splines  168  can be less than the height of the side wall  164 . 
     Each spline  168  comprises a width measured in a direction generally parallel to the top or bottom surface, and to the side wall  164  of the weight member  148 . In the illustrated embodiment, each spline  168  comprises approximately 3-10% of the length of one side of the trapezoidal weight member  148 . Other embodiments can have different spline widths. In some embodiments, the width can be roughly 3%, 4%, 5%, 6%, 7%, 8%, 9%, or 10% of the length of one side of the weight member  148 . 
     Each spline  168  comprises a height that is measured from an outermost edge of the spline  168  to the side wall  164  of the weight member  148 , in a direction generally perpendicular to the sidewall  164 . In many embodiments, the height of each spline  168  can range from 0.01 inches-0.30 inches. In some embodiments, the height of each spline  168  can range from 0.01 inches-0.05 inches, 0.05 inches-0.10 inches, 0.10 inches-0.15 inches, 0.15 inches-0.20 inches, 0.20 inches-0.25 inches, 0.25 inches-0.30 inches. Additionally, the height of each spline  168  can remain constant, or the height of each spline  168  can vary along the length of spline  168 . In the illustrated embodiment, the height of each spline  168  is smaller closer to the lower surface, and the height is larger closer to the upper surface  160 . In other embodiment, the height of the splines  168  can vary according to any profile (e.g. increase in a direction extending from the lower surface to the upper surface  160 , increase in a direction extending from the upper surface  160  to the lower surface, or any combination thereof). 
     The splines  168  function to secure the weight member  148  within the cavity  128 . The increasing height of each spline  168  along the length of each spline  168 , creates a press fit with the side surface  136  of the cavity  128 . As the weight member  148  is set into the cavity  128 , the splines  168  abut the side surface  136  of the cavity  128  and the weight member  148 . This abutment helps secure the weight member  148  in place within the cavity  128 . 
     b. Slits 
     Referring to  FIG. 3 , the weight member  148  can comprise one or more slits  172  located on and inset from the side wall  164  of the weight member  148 . The slits  172  are configured to receive the ribs  144  in the cavity  128  when the weight member  148  is positioned within the cavity  128  on the club head  100 . Accordingly, the slits  172  comprise a cross-sectional shape corresponding to the cross-sectional shape of the ribs  144 . 
     In the illustrated embodiment, the weight member  148  comprises three slits  172 . In other embodiments, the one or more slits  172  can comprise any number of slits  172 , including one, two, three, four, five, six, seven, eight or more slits  172 .

In the illustrated embodiment, the slit  172  does not extend entirely to the upper surface  160  of the weight member  148 . In other embodiments, the slit  172  can extend entirely to the upper surface  160  of the weight member  148 . 
     Each slit  172  has a height that is measured from the lower surface to the upper surface  160  of the weight member  148 . The height comprises between 50% and 100% of the height of the side wall  164 . In some embodiments, the height of the slit  172  can comprise 50%-75%, 60%-80%, 70%-90%, or 80%-100%. The height of the slit  172  can range from 0.10 inches to 0.25 inches. For example, the height of the slit  172  can range from 0.10 inches-0.15 inches, 0.15 inches-0.20 inches, or 0.20 inches-0.25 inches. In one embodiment, the height of the slit  172  can be approximately 0.20 inches-0.25 inches. The height of the slits  172  is substantially similar to the height to the of the ribs  144 , such that the slits  172  house the ribs  144  when the weight member  148  is positioned within the cavity  128 . 
     Each slit  172  has a width that is measured from opposing edges of the slit  172  that are adjacent or in contact with the side wall  164 . The width of the slit  172  can range from 0.03 inches to 0.20 inches. For example, the width of the slit  172  can range from 0.03 inches-0.05 inches, 0.05 inches-0.10 inches, 0.10 inches-0.15 inches, or from 0.15 inches-0.20 inches. The width of the slit  172  can be similar to or larger than the width of the rib  144 , as the slits  172  correspond to or mate with the ribs  144  protruding from the side surface  136  of the cavity  128  when the weight member  148  is positioned within the cavity  128 . 
     Each slit  172  corresponds to a rib  144  of the cavity  128 . The slits  172  surround each rib  144  and provide visual references to ease the placement of the weight member  148  into the cavity  128 . In addition, the slits  172  prevent the weight member  148  from rotating, shifting, or vibrating during installation or play.

     IV. Assembly 
     As illustrated in  FIGS. 5-7 , the multicomponent weight system  120  is assembled to the club head  100  within the cavity  128 . The multicomponent weight system  120  is positioned within the cavity  128  on the sole  104  of the club head  208  such that the cap  152  and the fastener  156  are flush with the external surface of the sole  104 , and there is no gap between the weight member  148  and side surface  136  of the cavity  128  of the sole  104 . 
     To assemble the multicomponent weight system  120  to the club head  100 , the weight member  148  is placed in the cavity  128  of the club head  100 . The cap  152  is then placed overtop the weight member  148 , and the fastener  156  is placed through the cap  152  and the weight member  148 , and into the fixing aperture  140  of the cavity  128 . The fastener  156  is then tightened, completing the assembly of the multicomponent swing weight system  120 . 
     In the illustrated embodiment, when the weight member  148  is positioned within the cavity  128 , the splines  168  of the weight member  148  contact the side surface  136  of the cavity  128 , and the ribs  144  of the cavity  128  align with the slits  172  of the weight member  148 .

     V. Materials 
     The weight member  148  can be made of any material, such as metals, polymers (e.g. thermoplastic polyurethane, thermoplastic elastomer), composites, or any combination thereof. The weight member  148  can be a polymer injection molded with different quantities of a high-density material (e.g. metal powder) or materials of different densities, to achieve weight members  148  of varying mass, while maintaining the same volume. Injection molded weight members  148  with different densities allow for a wide range of weight members  148  with an identical volume and geometric shape. 
     The volume, V, of an object can be calculated by Equation 1 below, wherein m is the mass of an object, and p is the density of an object. Mass and density are directly related. For example, if the volume is constant and the mass increases, then the density also increases. If the volume is constant and the mass decreases, then the density also decreases.

     The weight member  148  can have a constant volume, while changing the density of the material to increase the mass. In many embodiments the density of the weight member  148  ranges from 1.7 g/cc-10.8 g/cc. In some embodiments the density of the weight member  148  ranges from 1.7 g/cc-4.2 g/cc, 4.3 g/cc-6.7 g/cc, 6.8 g/cc-9.2 g/cc, or 9.3 g/cc-10.8 g/cc. 
     In many embodiments, the mass of the weight member  148  ranges between 2.0 g and 30.0 g. In some embodiments, the mass of the weight member  148  ranges from 2.0 g-4.0 g, 4.0 g-6.0 g, 6.0 g-8.0 g, 8.0 g-10.0 g, 10.0 g-12.0 g, 12.0 g-14.0 g, 14.0 g-16.0 g, 16.0 g-18.0 g, 18.0 g-20.0 g, 22.0 g-24.0 g, 24.0 g-26.0 g, 26.0 g-28.0 g, 28.0 g-30.0 g. The mass of the weight member  148  can be 2 g, 3 g, 4 g, 5 g, 6 g, 7 g, 8 g, 9 g, 10 g, 11 g, 12 g, 13 g, 14 g, 15 g, 16 g, 17 g, 18 g, 19 g, 20 g, 21 g, 22 g, 23 g, 24 g, 25 g, 26 g, 27 g, 28 g, 29 g, or 30 g. 
     In the illustrated embodiment, the weight member  148  comprises thermoplastic polyurethane (TPU). The TPU material allows for the weight member  148  to be compressed against the base  132  and side surface  136  of the cavity  128  when the downward force  228  of the fastener  156  is applied. This compression creates a press seal, preventing water, debris, or dirt from entering into the cavity  128  from the side surface. The TPU weight member  148  is further compressed as the fastener  156  passes through the through hole of the weight member  148 . The body portion  212  of the fastener  156  interacts with the weight member  148 , creating a seal within the aperture  176 , which prevents water or debris from entering the cavity  128  from the fastener  156  entry. 
     The durometer of a material measures the hardness of the material. In many embodiments, the material of the weight member  148  can have durometer range between 40D and 80D. In some embodiments, the durometer range can be between 55D and 75D. These durometers are optimal as they provided the desired amount of compression and rigidity. If the durometer is too low, the weight member  148  can be over compressed, compromising the structural integrity and causing the weight system to compress below the external sole contour  130 . If the durometer is too high, the weight system  120  does not compress, and there is no seal, or a poor seal created at the base  132  and side walls  136  of the cavity  128 . 
     The cap  152  can be made of metals such as steel, tungsten, aluminum, titanium, vanadium, chromium, cobalt, nickel, other metals, metal alloys, plastics, composites, or any combination thereof. For example, the cap  152  can be made of either 304SS or 6061-Al. Further still, the cap  152  may comprise a physical vapor deposition (PVD) or type II anodized finish, which can prevent grass, dirt, and debris from getting stuck in between the cavity  128  and the multicomponent weight system  120 . The PVD and type II anodized finish improves the wear performance of the sole  104  and the aesthetic appeal of the club head  100 . 
     The fastener  156  can be made of metals such as steel, stainless steel, tungsten, aluminum, nickel, other metals, metal alloys, or any combination thereof. For example, the fastener  156  can be made of 303SS or 304SS. Further, the fastener  156  may comprise a conversion coating to add corrosion resistance and minimize light reflection. For example, the conversion coating can be a black oxide coating. 
     VI. Benefits 
     The multicomponent weight system  120  allows a manufacturer to form weights of different mass, while maintaining a constant volume. As manufacturers create denser weight members, weight members become more brittle, often causing the weight members to crack or break over time. However, through the combination of the cap  152 , the fastener  156 , and the ribs  144  within the cavity  128 , if a weight member  148  cracks it will not compromise the moment of inertia (MOI) and center of gravity (CG) properties within the golf club head  100 , since the weight member  148  will not move within or fall out of the cavity  128 . The multicomponent weight system  120  allows the manufacturer to couple a wide range of weight members  148  of different densities to the same golf club head  100 , while preventing any material breakdown or cracking of dense weight portions. Further, the multicomponent weight system  120  allows the manufacturer to couple a wide range of weight members  148  of different densities to the same golf club head  100 , while maintaining a similar aesthetic appearance for each golf club head  100  and optimizing CG and MOI. 
     Further, the cavity  128  can be reduced in size and be positioned further back on sole  104  of the golf club head  100  compared to current swing weight systems. Since the weight member  148  can be made extremely dense, without concern for the weight member  148  becoming brittle and cracking, the multicomponent weight system  120  can have a smaller profile than current swing weight systems. A smaller profile allows the multicomponent weight system  120  to be placed closer to the perimeter of the club head  100 , thus improving CG position. Further, reducing the amount of internal structural mass used to support the multicomponent weight system  120  in the sole  104  allows additional mass to be positioned in other locations of the club head  100  to further increase club head MOI. The increased MOI leads to increased directional forgiveness of the club head  100  for off centered hits, thus improving the overall performance of the golf club head  100 . 
     The slits  172  and ribs  144  provide visual references to ease placement of the weight member  148  into the cavity  128 . The slits  172  surround the ribs  144  when the weight member  148  is placed in the cavity  128 . When the weight member experiences a force, the ribs  144  contact the slits  172 , thus preventing any rotation or movement. The combination of one or more slits  172  on the weight member  148 , with the one or more ribs  144  in the cavity  128  prevents the multicomponent weight system  120  from shifting, rotating, or vibrating during installation and/or play. Further still, the geometry of the splines  168  securely wedges the multicomponent weight system  120  into the cavity  128 . The series of splines  168  ensures that the multicomponent weight system  120  will not rotate or shift during installation and/or play by providing an outward force  224  onto the side surface  136  of the cavity  128 . The increasing height of each spline  168  along the length of each spline  168 , creates a press fit with the side wall  168  of the cavity  128 . As the weight member  148  is set into the cavity  128 , the splines contact the side wall  168 . This contact creates an outward force  224 , which helps secure the weight member  148  in place within the cavity  128 . As the cap  152  is attached, and the fastener  156  is gradually fixed, the weight member  148  is further forced down into the cavity  128  by a downward force  228 . As the weight member  148  is forced down into the cavity  128 , the part of the spline  168  with the largest height contacts the side wall  164 , thus providing an outward force  224  on the side wall  164 , and further securing the multicomponent weight system  120  in place. 
     The multicomponent weight system  120  is able to prevent rotation of the weight member  148  within the cavity  128 , due to combination of the slits  172 , ribs  144 , and/or splines  168 . The weight member  148  can thus be manufactured without the need for tight tolerances, since the slits  172 , ribs  144 , and/or splines  168  provide a tight fit of the multicomponent weight system  120  within the cavity  128 . Reduced manufacturing tolerances reduce manufacturing costs of the multicomponent weight system  120  compared to weight systems devoid of one or more of the described features. 
     When the downward force  228  of the fastener  156  is applied through the cap  152 , the material of the weight member  148  is compressed against the base  132  and side surface  136  of the cavity  128 . The compression of the fastener  156  and cap  152  on the upper surface  160  of the weight member  148  creates a press seal, preventing water, debris, or dirt from entering into the fixing aperture  140  or the side surface  136 . This press seal combined with the ribs  144 , slits  172 , and splines  168 , improve the wear characteristics of the golf club head  100  by providing a water-resistant seal on the base  132  of the cavity  128 . This seal improves the longevity of the golf club head  100 , by preventing water from entering the interior of the club head  100 . This press seal prevents corrosion of the golf club head  100 . The multicomponent weight system  120  achieves a watertight seal, without intricate and costly machining techniques.
