Value Collection TCI40750450 Tension Control Bolt 3/4-10

Product Description

The VALUE COLLECTION TCI40750450 is a tension control bolt engineered for structural steel connections requiring precise, inspectable preload. With a 3/4-10 UNC thread and 4.5 inches of length under the head, this fastener meets ASTM A490 and ASTM F2280 standards, making it appropriate for high-strength structural applications. The splined end shears off at a calibrated torque during installation, eliminating the need for torque wrenches or turn-of-nut verification. Each package includes the bolt, a compatible nut, and a washer. Installation is performed by licensed ironworkers or structural steel contractors working under applicable building codes.

This tension control bolt is used in structural steel framing for commercial and industrial construction, including moment frames, braced frames, and beam-to-column connections. It is suited for applications where AISC or RCSC bolting specifications are required and where torque-controlled pretensioning is mandated by the engineer of record. The bright, uncoated finish is typical for interior structural applications or where field painting will be applied after bolt installation.

Key Features

• Meets ASTM A490 and ASTM F2280 standards for high-strength structural bolting
• 3/4-10 UNC thread for standard structural connection compatibility
• 4.5 inches length under head accommodates typical multi-ply steel stack-ups
• Splined shear end enables single-sided installation with a TC wrench — no torque verification required
• Bright, uncoated finish — no coating to compromise friction coefficient in slip-critical joints
• Includes nut and washer for a complete fastener assembly per ASTM F2280

Compatibility

Designed as an OEM-style structural fastener for high-strength steel connections conforming to ASTM A490 and ASTM F2280 specifications; verify stack-up thickness and grip length requirements against project engineering drawings before installation.

Installation Notes

Installation must be performed by qualified ironworkers or structural bolting crews using a calibrated tension control wrench designed for 3/4-inch TC bolt assemblies. Ensure all mating steel surfaces are free of mill scale, burrs, and contaminants before assembly, particularly in slip-critical connections. Do not reuse bolts once the splined end has sheared. Follow RCSC Specification for Structural Joints and applicable local building code requirements throughout the installation process.
