These were a direct replacement for the studs holding down the inspection plates on the floor of my 1960 Cessna 172A. The quality is excellent and the price is very reasonable. Side note: I used a small screwdriver to slightly widen the three prongs in order to make them fit the holes better in a couple of sites, but this was due to the holes in the plates and floor widening slightly over the years.

Sure makes the annual go a lot quicker. Previous owner had screws in each inspection port. Now itâ??s a quick in and out.

Replaced the two dozen that had been lost over the years with these. Exact replacement for the originals, work perfectly.
