Value Collection TCB31000325 Tension Control Bolt A325

Product Description

The VALUE COLLECTION TCB31000325 is a structural tension control bolt designed for high-strength steel-to-steel connections in construction and fabrication applications. This fastener meets ASTM A325 and ASTM F1852 standards and is manufactured from Grade A325 steel with a bright, uncoated finish. The bolt features a 1-8 UNC thread size and a 3-1/4 inch length under the head, with a 1-7/8 inch head diameter. Each package includes a matching nut and washer, making it a complete fastening assembly ready for installation. Licensed structural ironworkers, steel erectors, and commercial construction crews typically work with this fastener type.

This tension control bolt is suited for structural steel connections in commercial, industrial, and heavy construction projects. The splined end design characteristic of ASTM F1852 tension control bolts allows installation using a TC wrench that shears the spline once the required pretension is achieved, eliminating the need for manual torque inspection on individual fasteners. This package contains 5 complete bolt assemblies, each including a nut and washer. It is appropriate for use wherever ASTM A325 high-strength bolts are specified on structural drawings.

Installation Notes

Installation of structural tension control bolts should be performed by qualified ironworkers or structural steel erectors in accordance with the AISC and RCSC Specification for Structural Joints Using High-Strength Bolts. A calibrated tension control wrench is required to properly shear the splined end and confirm required pretension. Inspect mating steel surfaces and hole alignment before snugging the assembly. Do not reuse tension control bolt assemblies once the spline has been sheared.
