Description

ASTM is an international organization for standard development. The ASTM (American Society for Testing and Materials) standard is an international standard for heavy-duty structural bolts and nuts.

This standard pertains to steel bolts with a minimum tensile strength ranging from 1040 to 1210 megapascals. Bolts manufactured according to this standard are typically made from alloy steels. This group of bolts specified in this standard is recognized as high-strength structural bolts. These bolts are produced in both metric and inch sizes. This standard is used for the production of hexagon bolts, stud bolts, anchor bolts, U-bolts, and special bolts. However, its primary application is for high-strength six-sided structural bolts.

The bolts covered by this standard are categorized into three types, with Type 2 being phased out since 2002. Type 1 is recognized as 10.9, and Type 3 is known as 10.9.3. Despite different chemical compositions in each type, the mechanical properties are similar in both types, necessitating different heat treatment operations for each type accordingly.
