Fixation with Threaded Rivet Nut Insert
Threaded rivet nut inserts (a.k.a.
rivnuts
) may be also used, especially on the
composite and thin panels. Again, they come in various forms. Some special
riveting tool is needed to fix the threaded rivet.
Get some aluminium M3 rivnuts. Drill a hole into the panel, as it is required
by the rivnut used. Then use the rivnut tool to fix the inserts. Be gentle, as
there is only minimal panel material between hole and the cutout chamfer.
Figure 7 shows an example.
There is a small disadvantage using rivnuts. As the rivnut head has some
minimal thickness, the Aetos bezel will probably not mount flush with the
panel – there will be a small gap.

Fixation with Spacer Stud and Epoxy
As another alternative, a M3 nut can be epoxied to the back of the instrument
panel. Standard M3 nut is a bit too small to be epoxied successfully. Thus a
M3 spacer stud at least 6 mm in length may be used instead.
1. The spacer surface shall be made rough using coarse sandpaper.
If
spacer is coated, the coat shall be removed. A dremel tool comes handy.
2. Sand the back side of the panel where epoxy will be applied. Surface
must be dull.
