Abstract:
A clamping screw (1) comprising:a hammer-shaped screw head (2) having a longitudinal axis (20) and a transverse axis (10) extending at a right angle to said longitudinal axis (20);a threaded screw shaft (3) connected to said screw head (2) and having a screw axis (16) extending perpendicularly to said longitudinal axis (20) and said transverse axis (10);said screw head (2) adapted to be inserted in a positive-locking manner into a T groove (4) of a construction component (25), whereby in a mounting position said screw head (2) extends transverse to a longitudinal slot (5) of the T groove (4);said screw head (2) having longitudinal sides (11) extending in a longitudinal direction defined by said longitudinal axis (20), said longitudinal sides (11) having first lateral surfaces extending perpendicularly to said transverse axis (10);said screw head (2) having terminal clamping portions (7) in said longitudinal direction for engaging support legs (6) that extend on both sides of the longitudinal slot (5) of the construction component (25);said clamping portions (7) each having a leading edge (12) in a rotational tightening direction (S) of said clamping screw (1) and a following blocking edge (13) for engaging a groove wall (14) of the T groove (4);said blocking edge (13) projecting from a plane of said first lateral surfaces;wherein a connecting line (15) between said leading edge (12) and said blocking edge (13) of a same one of said longitudinal sides (11) intercepts said transverse axis (10) of said screw head (2) at an angle .beta. that deviates from 90.degree..
