Description
Hex Bolts — ASTM A307 bolt for structural, machinery and general fastening. Complete with nut and washer on request. Stocked across common diameters and lengths in plain (black) and other finishes.
Hex bolts are the most common fastener in construction and fabrication — a hexagonal-headed threaded bolt driven and held with a spanner or socket. Their six-sided head gives good grip for tightening and is easy to reach from any angle, which is why hex bolts fasten nearly everything from steel frames and machinery to fixtures and equipment. They are available across a full range of sizes, grades and finishes to suit any duty.
Hex bolts are supplied in a wide range of diameters, lengths, grades and coatings, with matching hex nuts and washers. The right combination of size, grade and finish depends entirely on the load and environment — which is exactly why South-End carries the full range. See the specifications below for the sizes and grades on offer.
