M5 Hex Flange Nut Zinc Plated

A flange nut saves you fishing for a washer. The wide serrated base spreads the clamping load and grips the surface, so the nut holds its tension even when things rattle and move.

This one suits a M5 thread, made to DIN 6923 in zinc-plated steel for solid, everyday holding power. The teeth on the underside dig in as you tighten, which keeps the nut from backing off on trailers, machinery, and brackets that cop vibration.

Pair it with a matching flange bolt or any M5 thread. If you're not certain on the size, bring the bolt in and we'll match it for you.

Thread, pitch, and finish details are in the specs below.
