AISI 1020 Fasteners

AISI 4130 Bolts

BoltPort is a manufacturer & supplier of Carbon steel AISI 1020 Fasteners for general purpose bolting. AISI 1020 fasteners includes bolts, screws, stud bolts (studs), threaded rods, nuts, washers and custom fastening parts. These carbon steel fasteners are produced with complete metric and imperial size range with ISO, Unified UN, UNC, UNF, UNEF, BSW & BSF thread profiles. AISI 1020 boltings are produced by hot forming and machining to size.

Hex bolts, heavy hex bolts, stud bolts, threaded rods, double end studs, nuts, socket head cap screw, set screws and custom components are common products in AISI 1020 fasteners.

About AISI 1020

AISI 1020 is a low strength low hardenable general purpose carbon steel with tensile strength between 410-790MPa and Brinell hardness of 119 to 235. Carbon steel grade 1020 has high machinability, high ductility, high strength and good weldability. AISI 1020 is typically used in turned and polished or cold drawn condition. Steel grade 1020 is resistant to induction hardening or flame hardening due to its low carbon content. However carburization is possible in order to obtain case hardening. Hardness of Rc65 for smaller pieces an be attained, which is reduced with increase in object size.
