About this bolt
This is a bolt in 304 Stainless Steel, at strength class A2-70, supplied plain, with an M16 thread and a 40 mm length. 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 bolt passes through the parts it joins and is closed with a nut, so the joint is held by the clamp load the tightened bolt develops rather than by the shank itself. Bolts of this type are used on structural steelwork, machine frames, brackets, flanges and pipework — anywhere the joint has to come apart again for maintenance.
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.
Plain (self-colour) means no coating. On 304 and 316 stainless that is fine — the alloy passivates on its own. On carbon steel it will rust, so choose a coated option instead.
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.
