Flat Head Socket Screw, 6-40 x 3/8", Alloy Steel, Qty. 2

These are the screws you need to mount your red dot sight to your OEM SIG P320 slide with the RMR hole-pattern. Please note these are too short for Trijicon RMR/SRO. Most current versions of OEM SIG P320 slides (2021+) come predrilled with the RMR/Holosun hole pattern, but utilize 6-40 threads (AXG, AXG Scorpion, Legion, X-Series, Pro-Cut & Pro slides). 

It may be necessary to cut these to length for proper fit and to avoid interference with the extractor spring. Requires 5/64" Allen wrench (not included).

Includes: 2 #6-40 X 3/8" flat head, socket head screws.

No other tools or pins are included. Oil or anti-seize is recommended before installing. Use Loctite and follow red dot manufacturer's torque spec.

COUNTRY OF ORIGIN: Taiwan (may vary, depending on availability).

    They where not the right thread pitch I needed I have a sig p320 xten with rmr cut. >>>>>AB PROTOTYPE RESPONSE: current production SIG slides (2022+) use 6-40 threaded for the RMR footprint. The slides are not always countersunk deep enough to start the screw easily. It takes some proper alignment to get the screw threaded into the slide. 3/8" length is for Holosun 407C/507C, .410" is for Trijicon RMR/SRO
