M6 x 16 cm Serrated Flange Bolt, 304 Stainless Steel - XFBA2M6X16

Made in 304 (A2) stainless steel, the Hex Serrated Flange Bolt DIN6921 is a hex head bolt with a built-in flange under the head. The flange spreads the load like a washer, and the serrations bite into the surface to resist loosening.

Made from 304 (A2) stainless steel, a standard austenitic grade with good everyday corrosion resistance. It is a sound choice away from the coast; in chloride-exposed settings, step up to 316 (A4). Metric sizes are written M followed by the nominal thread diameter in millimetres, so M10 is a 10 mm thread.

This listing has 12 variants covering sizes M6 to M10 and lengths 16 cm to 40 cm. Every size comes in packs of 100.

Austenitic stainless steel is generally non-magnetic, although cold-worked parts can show weak magnetism. In wet conditions, keep stainless steel apart from aluminium and galvanised steel with a washer or sleeve, to reduce the risk of galvanic corrosion.

Key specifications

Selecting the right option

The serrations mark the surface they bite into, so they are not suited to painted or polished finishes you need to keep intact. Use a flat washer instead where a clean finish matters.
