M8 x 30 mm Security Post Torx Metal Thread Screw, 304 Stainless Steel - YCXSA2M8X30

The Security Countersunk Post Torx Metal Thread Screw, Stainless Steel is available in 26 sizes (M4 to M10) and is a post Torx security screw with a Torx recess that includes a centre pin, so it needs a matching security Torx bit to drive it. It has a metal (machine) thread for a nut or tapped hole..

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 26 variants covering sizes M4 to M10 and lengths 10 mm to 60 mm. Every size comes in packs of 100.

Austenitic stainless steel is generally non-magnetic, although cold-worked parts can show weak magnetism. Use stainless washers and nuts with stainless fasteners, so the whole joint is made of the same material.
