These screws are for mounting your Trijicon RMR onto your FN America FNX Series Firearm. 
These are High Strength machine screws with a T15 Torx flat head.
I use these screws on my own FNX 45
I could not find 1/4" S/S screws, so you will get the 1/4" black oxide screws for the adaptor plate.

You will get:
(2) 1/2" long S/S screws for mounting the RMR.
(2) 1/4" long Black Oxide screws for the cover plate.
100% Guaranteed to fit !
