A MS hex bolt (mild steel hexagon bolt) is a low-carbon-steel bolt with a six-sided head, supplied self-colour (plain) or zinc-plated and chosen for its strength, workability and low cost. Made to DIN 931 (partially threaded) and DIN 933 (fully threaded), it is supplied in mild steel grades — 4.6, 4.8 and 8.8 — and in coarse, fine thread and UNC, delivering dependable clamping force for general structural and mechanical joints.
Hamza Fasteners supplies mild steel hex bolts from M6 to M40 in a full range of lengths, ideal for steel structures, cladding, scaffolding, tank fabrication, MEP works and general fabrication. Bare mild steel is best kept to dry, indoor and general structural use; for outdoor, damp or coastal conditions we recommend galvanized, HDG or stainless bolts, which Hamza also supplies.
