A spacer assembly for spacably coupling a first and second component with a threaded connection bolt , each one of the first and second component provided with one or more fitting apertures , comprising: a support member , comprising a planar support plate having a through-hole with an internal support thread configured to threadingly engage with the threaded connection bolt , and a first clip portion projecting from a first support plate end in a direction substantially normal to said planar support plate , said support member being releasably mountable to the first component so as to axially align said through-hole with a first one of the one or more fitting apertures of the first component , during use; a base member , comprising a planar base plate having an upper surface and a lower surface opposite said upper surface , a cylindrical through-hole mount with an internal mount thread projecting from said upper surface in a direction substantially normal to said planar support plate to a predetermined mount length,; a spacer member , comprising a cylindrical body having a central axis and an external spacer thread , configured to operably engage with said through-hole mount (204 so as to axially move said spacer member (300 relative to said base member when rotating said spacer member relative to said base member , and an axial through-hole with a plurality of inwardly projecting resilient friction elements configured to provide an interference fit engagement with a predetermined friction force with the threaded connection bolt , during use; wherein the thread-engagement between said internal mount thread and said external spacer thread is opposite to the thread-engagement between said internal support thread and the threaded connection bolt , wherein said base member comprises an aperture at a first base plate end configured to receive and movably retain said first clip portion , during use. a support member , comprising a planar support plate having a through-hole with an internal support thread configured to threadingly engage with the threaded connection bolt , and a first clip portion projecting from a first support plate end in a direction substantially normal to said planar support plate , said support member being releasably mountable to the first component so as to axially align said through-hole with a first one of the one or more fitting apertures of the first component , during use; a base member , comprising a planar base plate having an upper surface and a lower surface opposite said upper surface , a cylindrical through-hole mount with an internal mount thread projecting from said upper surface in a direction substantially normal to said planar support plate to a predetermined mount length,; a spacer member , comprising a cylindrical body having a central axis and an external spacer thread , configured to operably engage with said through-hole mount (204 so as to axially move said spacer member (300 relative to said base member when rotating said spacer member relative to said base member , and an axial through-hole with a plurality of inwardly projecting resilient friction elements configured to provide an interference fit engagement with a predetermined friction force with the threaded connection bolt , during use; wherein the thread-engagement between said internal mount thread and said external spacer thread is opposite to the thread-engagement between said internal support thread and the threaded connection bolt , wherein said base member comprises an aperture at a first base plate end configured to receive and movably retain said first clip portion , during use. <EOS>
