What is a325 bolt

ASTM A is an ASTM International standard for heavy hex structural bolts, titled Standard Specification for Structural Bolts, Steel, Heat Treated, / ksi . Prior to its withdrawl in , the ASTM A specification covered high strength heavy hex structural bolts from 1/2″ diameter through /2″. ASTM A bolts are more commonly specified by engineers for use in structural steel connections on heavy construction projects, while SAE.
