ASTM A325 Hex Head Screws em ol hevi hex straksa bolt we ol i wokim bilong givim strongpela 'clamping force' na bikpela 'load capacity' long ol 'steel connection'. Ol i save yusim wantaim ol hevi 'hex nuts' na ol 'structural washer', na dispela i mekim gutpela wok long ol 'tension-critical' o 'shear-critical' asembli.
