ASTM A307 Grade A Stud Bolts

ASTM A307 Grade A Stud Bolts are fasteners made from low-carbon steel and consist of a length of rod that is threaded on both ends or fully threaded (all-thread studs). Unlike standard bolts, they are designed to be used with a nut on both ends, commonly for flange connections or anchoring where through-bolting is required. The A307 specification covers general-purpose applications where moderate strength is acceptable, requiring a minimum tensile strength of 60 ksi. These threaded studs are widely used in non-critical applications across many industries, including plumbing, general construction, and light machinery, providing a reliable and cost-effective joining solution. Zeron Fasteners manufactures and supplies A307 Stud Bolts in various lengths and protective finishes, ensuring compatibility with standard nuts and washers.
