Heat Treated Structural Steel Bolts SA-325 Minimum Tensile Strength 120/105Ksi

This standard applies to two types of quenched and tempered structural steel bolts, with a minimum tensile strength of 120Ksi for size ≤ 1 "and a minimum tensile strength of 105Ksi for size> 1. The supply size of bolts is 1/2 "~ 1-1/2". The size standard of bolts is generally ASMEB18.2.1 or B18.2.6 heavy series. Matching nuts are generally used first A563 carbon steel and alloy steel nuts. F436 type I hardened gasket is generally used as the matching gasket. The test method is preferred to the full-size tensile test.
