Red dot screws

This collection contains screws for red dots, plates and mounts. You need them when you lose or damage the original screws, or when the screws of the pistol maker do not fit your red dot.

Screws at a glance

How to read the title

In "6-32 x 0.374" [T10]", 6-32 is the thread, 0.374" the length and T10 the Torx bit. Threads 4-40, 6-32, 6-40 and 6-48 are imperial. M3, M3.5 and M4 are metric. A screw that is too long can bottom out before it clamps the red dot. A screw that is too short holds only a few threads.

Screws for specific models

CZ makes screws for its Optics Ready plates and Holosun for its K-series footprint. Shield Sights makes sets for its Glock MOS mount, RMR adapter plate, Walther mounts and mini sights, and for the Sig P320, the Sig P365 X and XL and the S&W M&P Shield Plus plates.

Put a drop of threadlocker on every screw. See Installation tools.

Frequently asked questions

Which screws do I need?

The same thread and length as your original screws. Measure them or check the manual of your red dot, then take the set with the same thread and length.

Do I need threadlocker?

Yes. Without it, the screws can loosen under recoil.
