About this rivet

This is a rivet in 304 Stainless Steel, at strength class A2-70, supplied plain, with an M3 thread. Every dimension is stated against the standard named above; where a tolerance class matters to your design, ask us and we will confirm it in writing before you order.

A rivet is a permanent fastener: it is set once and removed only by drilling it out, which makes it cheap and tamper-resistant but not serviceable. Used on sheet metal, ducting, panels, luggage hardware and light structures where the joint is never meant to be opened.

304 (EN 1.4301, A2) is the general-purpose austenitic stainless grade: good resistance to fresh water, food acids and atmospheric corrosion, non-magnetic in the annealed state. It is the default for indoor and general outdoor fastening where chlorides are low.

M3 is a metric thread with an 3 mm nominal diameter and a coarse pitch of 0.5 mm (ISO 261). A standard hex head takes a 5.5 mm spanner across the flats.

Is this not quite the size or grade you need? Ask us — we produce small batches to drawing and to DIN, ISO, GB and JIS standards, and we consolidate pallet and container loads for trade orders.
