Value Collection TCI40870325USA Tension Control Bolt 7/8-9

Product Description

The VALUE COLLECTION TCI40870325USA is a structural tension control bolt designed for high-strength steel-to-steel connections in construction and industrial applications. It features a 7/8-9 UNC thread, a 3-1/4 inch length under head, and a 1-5/8 inch head diameter. Manufactured from A490 alloy steel with a bright uncoated finish, this fastener meets ASTM A490 and ASTM F2280 standards. Each package includes the bolt, a compatible nut, and a washer. Structural ironworkers and steel erectors install these fasteners wherever high-strength bolted connections are specified by engineering drawings or steel construction codes.

Tension control bolts are used in structural steel framing for commercial and industrial construction. They are specified in connections requiring controlled bolt pretension, such as moment frames, column splices, and beam-to-column connections. This fastener ships in a package quantity of five, making it suitable for small-lot procurement or sample ordering. Installation is performed by qualified structural ironworkers following AISC and RCSC connection specifications.

Key Features

• 7/8-9 UNC thread for standard structural bolt hole patterns

• 3-1/4 inch length under head accommodates standard structural steel stack-ups
• Bright uncoated finish suitable for painted or galvanized contact surfaces
• Includes matching nut and washer for complete installation
• Package quantity of 5 per unit for flexible ordering

Compatibility

Designed as a direct-fit structural fastener for high-strength bolted connections requiring ASTM A490 and ASTM F2280 compliant tension control bolts with 7/8-9 UNC threading.

Installation Notes

Installation of tension control bolts must be performed by qualified structural ironworkers in accordance with RCSC Specification for Structural Joints requirements. Use a compatible TC bolt installation tool that engages the splined end to achieve the specified pretension. Do not reuse tension control bolts once the splined end has been sheared. Consult the project structural engineer of record and applicable building codes before substituting bolt grades or lengths.
