Hex Head Bolts M3–M8 — A2 Stainless DIN 933 (Pack of 10)

Why choose these A2 stainless hex head bolts

Fully-threaded hex head bolts — the standard spanner-driven fastener for most bolted joints. DIN 933 full-thread construction lets you clamp variable thicknesses with the same length, making these bolts ideal for repairs and adjustable fittings. A2 stainless steel handles interior, workshop and light outdoor use without rusting, and pairs neatly with our A2 hex nuts, nyloc nuts and washers.

Sizes available

Five bolt diameters — M3, M4, M5, M6 and M8 — across twelve length options from 10mm up to 100mm. Choose the length to clear your workpiece plus enough thread to engage all the nut’s height (typically the diameter plus 3–5mm).

Pack option

Supplied in packs of 10 per size. Add matching A2 nuts and washers from the Fasteners range to complete the joint, and mix sizes in one checkout to qualify for free UK delivery on orders over £20.

Typical uses

General workshop and trade repairs, machinery brackets, electrical enclosures, garden furniture, allotment and shed work, exhibition stand assembly, bicycle and motorcycle fittings, automotive accessory mounting and any spanner-driven bolted joint where a standard hex head is preferred.

How to fit

Pass the bolt through a clearance hole sized to match the thread diameter, run a matching nut down by hand and tighten with two spanners to firm but not crushing torque. Add a flat washer under the nut for load spread, or a serrated / nyloc nut for vibration resistance. Avoid over-torquing small sizes — A2 stainless is softer than carbon steel.
