M3 x 10 mm Hex Set Bolt, 304 Stainless Steel - XHSA2M3X10

The Metric Hex Set Bolt (Full Thread), 304 Stainless Steel is a hex head bolt threaded along its full length (also sold as a hex set screw). The full thread lets it run right up to the head and suits tapped holes and thin joints.

The range runs to 183 variants, covering sizes M3 to M24 and lengths 8 mm to 150 mm. Variants are supplied in packs of 10 to 100, depending on size.

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

A fully threaded bolt is the usual choice for tapped holes. Where the joint is loaded sideways, a partly threaded hex bolt keeps a plain shank in the shear plane. Use anti-seize on the thread, because stainless threads can gall when tightened. For coastal or chloride-exposed use, choose the A4 (316) version: Metric Hex Set Bolt (Full Thread) - 316 Stainless Steel.
