The most common heavy hex head screw, these steel screws meet ASTM A325 regulations for structural joints, such as mating I-beams and scaffolding. Material meets ASTM F3125 specifications for quality. Dimensions meet ASME B18.2. 6 specifications. Length is measured from under the head. ASTM A325 Structural Bolts and SA 325 Type 3 Hex Bolt ASTM F3125 Grade A325 Anchor Bolt and ASTM A325 Type 3 Stud Bolt manufacturer in India A tension control bolt (TCB Bolt) or a A325 Structural Bolts is a heavy duty fastener that is used in steel frame construction. The head is of the tension control bolt is usually constructed in the shape of a dome.
Specification ASTM A325 for High Strength Structural Bolts was withdrawn in May 2016, and replaced by ASTM F3125. Today, A325 is a grade of ASTM F3125 Bolts. ASTM F3125:Standard Specification for High Strength Structural Bolts and Assemblies, Steel and Alloy Steel, Heat Treated, Inch Dimensions 120 ksi and 150 ksi Minimum Tensile Strength ASTM F3125 Grade F2280 (A490-TC) - Boulons PlusASTM F3125 Grade F2280 (A490 TC) Structural bolts, steel, heat treated, 120 ksi minimum tensile strength. The ASTM F3125 Grade F2280, (Also known as A490 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 ASTM F3125-A325 - Precision BoltsJan 25, 2017 · ASTM A325 (F3125) Structural bolts, steel, heat treated, 120/105 ksi minimum tensile strength. The ASTM A325 specification covers 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.

In 2016, ASTM F3125 replaced ASTM A325 and ASTM A490 which are now grades under the new ASTM F3125 Standard. ASTM A325 and ASTM A490 are still widely used terms throughout the industry.
- 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 faTypes ASTM A325ASTM F3125 is a specification covering the chemical, physical and mechanical requirements for structural bolts and will eventually replace all six ASTM structural bolt standards, including A325. Structural Bolts Tension Control & Heavy Hex Bolts Jun 29, 2020 · ASTM F3125 covers high strength structural bolts including Grades A325 and A490. These bolts are designed for steel-to-steel structural connections and include heavy hex bolts and tension control bolts. Birmingham Fastener houses the nations largest inventory of structural bolting components, both domestic and imported.ASTM F3125 Specification - Boltport FastenersASTM F3125 is a standard material specification covering chemical, physical and mechanical requirements for quenched and tempered bolts manufactured from steel and alloy steel in inch dimensions, in two strength grades, two types and two styles.
