The ASTM A325 specification covers high strength heavy hex structural bolts from ½ 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. Refer to the Structural Bolts page of our site for thread lengths and other related dimensions. ASTM A325 Baden Steelbar & Bolt Corp.ASTM A325. A325 was a ASTM International specification for heavy hex structural bolts. A325 had covered high strength heavy hex structural bolts 1/2" through 1-1/2" in diameter. It was withdrawn in 2016 and became a grade of F3125. However, A325 is still commonly referred to, so it is listed here for reference. ASTM A325.

ASTM F1136 coating usage was added to the Specification. References to ASTM A153 have been replaced with an updated reference to ASTM F2329. Section 3.3 was modified to provide a clarification on thermally-cut holes. Section 3.4 was modified in regard to burrs over z in. high. Structural Bolts Fastenal
- Turn-Of-NutAlternative Design BoltsWasher ControlCalibrated Wrench MethodThis method involves tightening the fastener to a low initial "snug tight" condition and then applying a prescribed amount of turn to develop the required preload. The actual preload will depend on how far the nut is turned as well as how much preload was established prior to the turning. 1. Snug the joint to bring the assembly into firm contact. Apply a few impacts with impact wrench until solid sound or apply full effort with a spud wrench. 2. Inspect the joint to verify "snug tight". 3. Match mark bearing face of ASTM F3125 Grade F1852 (A325-TC) - Boulons PlusASTM F3125 Grade F1852 (A325 TC) Structural bolts, steel, heat treated, 120 ksi minimum tensile strength. The ASTM F3125 Grade F1852, (Also known as A325 TC bolts) specification cover heat treated, steel, tension control bolt-nut-washer assemblies, also referred to as sets.These assemblies are capable of developing a minimum predetermined tension when installed by applying torque to the
