A hot dipped galvanized hex bolt (HDG hex bolt) is a carbon-steel bolt with a six-sided head, coated by immersion in molten zinc for a thick, tough, metallurgically-bonded layer that far outlasts electro-galvanizing in harsh conditions. Made to DIN 931 (partially threaded) and DIN 933 (fully threaded), it is supplied in strength grades — 4.6, 8.8 and 10.9 — and in coarse, fine thread and UNC, delivering high tensile strength and dependable clamping force for demanding structural and mechanical joints.
Hamza Fasteners supplies HDG hex bolts from M6 to M40 in a full range of lengths for structural steel, outdoor infrastructure, coastal and marine works, towers, cladding, tank fabrication and MEP. The thick hot-dip zinc gives the longest-lasting corrosion protection for exposed and salt-laden environments across the Gulf. Pair with HDG hex nuts and washers for a fully weatherproof joint.
