Value Collection TCI40870475 Tension Control Bolt A490

Product Description

The VALUE COLLECTION TCI40870475 is a structural tension control bolt designed for high-strength steel-to-steel connections in construction and industrial applications. This 7/8-9 UNC threaded fastener measures 4-3/4 inches under the head and is manufactured from Grade A490 steel, meeting ASTM A490 and ASTM F2280 standards. Each bolt arrives as a complete assembly including a compatible nut and washer, ready for direct installation. The uncoated bright finish is standard for structural steel applications where field painting or coating will be applied after erection. Licensed ironworkers and structural steel contractors are the primary installers.

This tension control bolt is suited for structural steel framing in commercial and industrial construction, including beam-to-column connections, moment frames, and bolted splice plates. The 7/8-9 thread size is among the most common specifications called out in structural steel connection designs. Package quantity is 5 assemblies per unit.

Designed as an OEM-style structural replacement fastener for 7/8-9 UNC tension control bolt applications conforming to ASTM A490 and ASTM F2280 specifications.

Installation Notes

Tension control bolts are installed by licensed ironworkers or structural steel contractors using a shear-wrench tool that engages the splined end of the bolt and shears it off at the specified tension — no torque wrench calibration is required by design. Follow AISC and RCSC bolt installation specifications, including inspection requirements for pre-installation verification and rotational capacity testing. Never reuse tension control bolts once the splined end has been sheared. Ensure mating surfaces are free of mill scale, paint, and debris as required by the connection design documents.
