M3 x 6 Torx Socket Cap Screw, 304 Stainless Steel - TCSA2M3X6

The Torx Socket Cap Screw A2 (304) is a cylindrical-head screw driven by a six-lobe Torx recess. The Torx drive grips the bit more fully than a hex key, which reduces slipping (cam-out) and rounding of the recess.

You can choose from 81 variants, covering sizes M3 to M8 and lengths 6 to 150. Pack quantities depend on size: packs of 25 to 100.

The A2 (304) stainless material suits indoor, fresh water and typical outdoor use. Where the fastening is exposed to salt air, pool chemicals or marine conditions, A4 (316) is the grade to use instead. Metric sizes are written M followed by the nominal thread diameter in millimetres, so M10 is a 10 mm thread.

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

Use a Torx bit that matches the recess size exactly. Sizes are shown on the variant. Use anti-seize on the thread, because stainless threads can gall when tightened.
