Kydex Customs Spare M-LOK Screw Set — ten bolts, ten T-nuts and an Allen key. 4140 steel hardware in the standard 12mm length, for any M-LOK accessory.

M-LOK T-nuts are small, black and designed to fall into long grass. Anyone who has fitted and refitted a handguard knows the pack of ten is not optimism, it is experience. This set covers several accessories and leaves spares over.

The T-nut is the part that does the work in an M-LOK slot — it drops through, rotates 90° and locks against the inside of the rail. Steel matters here because that rotation is what takes the load, and a soft nut deforms into the slot rather than gripping it.

Bolts are 4140 steel at the standard 12mm length, and an Allen key is included so nothing else is needed to fit them.

Frequently asked questions

Will these fit KeyMod? No. The two systems use completely different hardware — the KeyMod set is sold separately.

Which way round does the T-nut go? Through the slot, then rotated a quarter turn so the long axis of the nut sits across the slot. If it will not tighten, it has not rotated.

Why steel rather than aluminium? Because the T-nut takes the clamping load on its edges. Aluminium deforms there and the accessory works loose.

💡 Titan Forge Airsoft tip: Snug both bolts before fully tightening either — tightening one fully first can pull the accessory out of square on the rail. More in Rifle Accessories.
