Value Collection TCB30750175USA-005BX Tension Control Bolt

Product Description

The VALUE COLLECTION TCB30750175USA-005BX is a Grade A325 structural tension control bolt used in steel-to-steel connections that require precise clamping force. The bolt features a 3/4-10 UNC thread and measures 1-3/4 inches in length under the head, with a 1-3/8 inch head diameter. The splined shear-type end allows installation with a standard TC bolt gun, which shears the spline tip at the correct tension without requiring torque verification. Each package includes a compatible nut and washer. Ironworkers, structural steel erectors, and certified bolting specialists are the primary installers for this fastener type.

This tension control bolt is used in structural steel framing applications including commercial and industrial construction, pre-engineered metal buildings, and steel bridge connections. It conforms to ASTM A325 and ASTM F1852 standards, making it suitable for standard and high-strength structural joints. The bright, uncoated finish is typical for indoor or protected steel connections. Each package contains 5 complete bolt assemblies, each including a nut and washer.

Key Features

• Grade A325 structural steel construction meets high-strength fastener requirements
• Conforms to ASTM A325 and ASTM F1852 fastener standards
• 3/4-10 UNC thread with 1-3/4 inch length under head

• Includes matching nut and washer in each assembly
• Bright, uncoated finish — suitable for protected or interior structural connections

Compatibility

Designed for use in structural steel connections requiring ASTM A325 or ASTM F1852 compliant 3/4-10 UNC tension control bolt assemblies.

Installation Notes

Tension control bolts are installed by ironworkers or certified structural bolting crews using a TC-type shear wrench or electric bolting tool. The splined tip shears flush when the bolt reaches the required pretension, eliminating the need for torque wrench verification. Follow AISC and RCSC specification requirements for hole preparation, washer placement, and inspection. Never reuse a tension control bolt assembly once the spline tip has been sheared.
