Thread rolling of the SA 453 gr 660 Socket Head Bolts is a cold working process. Here a machined blank is compressed between reciprocating or rotating dies. The thread profile of the ASTM A453 Grade 660 A Socket Head Cap Screws is penetrated by dies. Metal flows through the cavities creating a thread profile.

The threading of the ASTM A453 660d Anchor Bolts is more efficient and less costly. The process imparts a superior finish on the threaded flanks. The ASTM A453 gr 660 d Anchor Rods offer better accuracy and allow for a higher rate of production. The process also eliminated the loss of metal due to chipping. The cold rolling of the A453 660b Square Bolts strengthens its ultimate tensile strength.
