A325 Structural Bolt Specifications

This specification covers two types of quenched and tempered steel heavy hex structural bolts having a minimum tensile strength of 120 ksi for sizes 1 0 in.

A325 structural bolt specifications.

Formerly under the jurisdiction of committee f16 on fasteners this specification was withdrawn in may 2016 and replaced by specification f3125 f3125m. Astm a325 is an astm international standard for heavy hex structural bolts titled standard specification for structural bolts steel heat treated 120 105 ksi minimum tensile strength it defines mechanical properties for bolts that range from 1 2 to 1 1 2 inches 13 to 38 mm in diameter. Prior to its withdrawl in 2016 the astm a325 specification covered high strength heavy hex structural bolts from 1 2 diameter through 1 1 2 diameter. These bolts are intended for use in structural connections and therefore have shorter thread lengths than standard hex bolts.

If you are working with a325 structural bolts on a regular basis we strongly recommend purchasing a copy of the astm a325 specification from astm international. The equivalent metric standard is astm a325m which is titled standard specification for.
