Value Collection TCB31000475 Tension Control Bolt A325

Product Description

The VALUE COLLECTION TCB31000475 is a structural tension control bolt designed for high-strength bolted connections in steel construction. Manufactured to ASTM A325 and ASTM F1852 standards, this bolt features a 1-8 UNC thread and measures 4-3/4 inches in length under the head with a 1-7/8 inch head diameter. Each package includes a matching nut and washer, making it a complete fastener assembly ready for installation. This fastener is installed by ironworkers and structural steel erectors on commercial and industrial building projects where controlled-tension bolting is required by specification.

This tension control bolt is suited for structural steel framing applications in both commercial and industrial construction. The splined end design allows installation with a standard TC bolt gun, which shears the spline tail when the specified preload is reached, confirming correct tension without the need for torque wrenches or turn-of-nut verification procedures. Each package contains 5 complete assemblies including nut and washer.

Compatibility

Designed as an ASTM F1852 compliant tension control bolt assembly for use in structural steel connections requiring ASTM A325 high-strength fasteners under AISC and RCSC bolting specifications.

Installation Notes

Installation is performed by qualified ironworkers or structural steel erectors using a pneumatic or electric TC bolt gun matched to the bolt diameter. The connection must be brought to a snug-tight condition before final tensioning. Power down all adjacent equipment and follow applicable OSHA fall protection and lockout/tagout procedures during overhead or elevated steel work. Consult RCSC Specification for Structural Joints Using High-Strength Bolts for hole preparation, faying surface, and inspection requirements.
