Value Collection TCB30750425USA Tension Control Bolt A325

Product Description

The VALUE COLLECTION TCB30750425USA is a 3/4-10 UNC tension control bolt manufactured from A325 structural steel with a bright uncoated finish. This fastener measures 4.25 inches in length under the head and features a 1.375-inch head diameter. Tension control bolts use a splined end that shears off at a calibrated torque, providing a reliable visual confirmation that the correct clamp load has been achieved. Each package includes a compatible nut and washer. These fasteners are installed by ironworkers and structural steel erectors on commercial and industrial steel construction projects.

Tension control bolts are used in structural steel connections where consistent preload is required. The 3/4-10 thread size and A325 grade rating make this bolt suitable for standard structural steel bolting applications including beam-to-column connections, moment frames, and braced frames. The package quantity of 5 fasteners per unit is appropriate for small-run procurement or jobsite replenishment. This fastener meets ASTM A325 and ASTM F1852 standards.

Compatibility

Designed as an ASTM F1852-compliant tension control bolt for standard structural steel bolting applications where 3/4-10 UNC A325-grade fasteners are specified.

Installation Notes

Tension control bolts require an electric or pneumatic TC bolt installation tool with the appropriate socket set to engage the splined tip. Power down or de-energize any nearby equipment before working in energized areas on steel structures. Installation must comply with the AISC Specification for Structural Steel Buildings and applicable project specifications. Do not reuse tension control bolts once the splined end has sheared.
