Value Collection TCI40750300 Tension Control Bolt 3/4-10 A490

Product Description

The VALUE COLLECTION TCI40750300 is a structural tension control bolt designed for high-strength bolted connections in steel construction. It features a 3/4-10 UNC thread and measures 3 inches in length under the head with a 1-3/8 inch head diameter. Manufactured from A490 steel and supplied in a bright uncoated finish, this bolt meets ASTM A490 and ASTM F2280 standards. Each package includes a matching nut and washer, making it a complete fastener assembly ready for installation. Licensed structural trades and ironworkers rely on this type of tension control bolt where precise pretension is required without the use of a torque wrench.

This tension control bolt is used in structural steel connections on commercial, industrial, and infrastructure projects. The splined end design allows installation with a standard TC gun, shearing the spline when the correct pretension is reached. Typical applications include beam-to-column connections, moment frames, and braced frame assemblies. The A490 grade rating makes it suitable for use with high-strength structural steel members where ASTM F2280 compliance is specified by the engineer of record.

Compatibility

Designed as an OEM-style structural fastener for high-strength bolted steel connections requiring ASTM A490 and ASTM F2280 compliant tension control bolt assemblies.

Installation Notes

Installation is performed by qualified structural ironworkers or steel erectors using a calibrated TC gun that engages the splined tail to apply and verify pretension. Power down all adjacent energized systems before working in proximity to electrical infrastructure on job sites. Follow AISC and applicable local structural code requirements for bolt pretensioning procedures, inspection, and documentation. Do not reuse tension control bolts once the spline has been sheared.
