Specification in detail:

This standard is applicable to two types of heavy structural steel bolts with quenching and tempering treatment, with tensile strength of 150Ksi~173Ksi.

The supplied dimensions of bolts are 1/2"~1-1/2". The size of bolts generally follow ASME B18.2.1 or B18.2.6 heavy series.

A563 carbon steel and alloy steel nuts are usually used for matching nuts.

F436 typeⅠhardening treated gaskets are usually chosen as matching washers.

Full-size tensile test is the first choice as the test method.
