SPT's E-Z Nuts
If you have ever installed
instruments behind an
aircraft panel, you probably swore at the guy who developed those clip-on
"cage-type" instrument nuts. They can fall off when you push in the screw (and
you love the clinking sound of a nut falling off behind the instrument and the
resulting 15 minute search for the *!!!* nut?). Clip-on nuts have a tendency to get out of
alignment, strip out and cause radio
interference (just kidding on the last one). Since the clip-on nuts come
in 8 different sizes (determined by instrument flange thickness), the chances are slim that you will have all
the needed sizes
in stock. NOTE: Each EZ Nut comes with four 1 1/2" black stainless
steel screws and for black nylon washers.
The advantages of the E-Z Nuts are numerous:
E-Z Nuts simply slip over the instrument and E-Z
Nuts are held in place during installation with 3M adhesive--they won't
fall off and get lost.
Line up one screw hole and then all four are lined up--this
is a big advantage when you have one hole that is inaccessible.
E-Z Nuts come in two obvious sizes (3 1/8" and 2
1/4" that fit the standard aircraft instruments (you won't have to
guess what the thickness is of the instrument flange that is behind the
panel--"cage type" nuts come in 8 different sizes).
The threaded E-Z Nuts are stainless steel and
have more threads and will not strip out easily, unlike the thin, brass,
threaded plate on the "cage-type" of nut
Misalignment and cross threading of the
"cage-type" of nut is common, this will not happen with the larger
E-Z Nut bezel that is held flat against the backside of the
