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.
