Value Collection TCI40750375 Tension Control Bolt 3/4-10 A490

Product Description

The VALUE COLLECTION TCI40750375 is a structural tension control bolt designed for high-strength steel-to-steel connections in construction and fabrication applications. Manufactured from Grade A490 steel with a bright, uncoated finish, this bolt uses a splined end break-off design that indicates proper installation tension without the need for torque wrenches or direct-tension indicators. The 3/4-10 UNC thread and 3.75-inch length under head make it suitable for heavy structural connections requiring precise, consistent clamping force. Each package includes a matching nut and washer. Compliant with ASTM A490 and ASTM F2280 standards.

Tension control bolts are used in structural steel framing, beam-to-column connections, bridge construction, and industrial fabrication where verified bolt tension is required by specification. This bolt is installed using an electric TC bolt gun that engages the splined shank end and shears it off once the design tension is achieved. The uncoated bright finish is appropriate for indoor structural applications or where a coating is applied after assembly. The included nut and washer are matched to the bolt grade and thread.

Key Features

• Grade A490 high-strength steel construction meets ASTM A490 and ASTM F2280 specifications
• 3/4-10 UNC thread with 3.75-inch length under head for substantial structural connections
• 1.375-inch head diameter provides broad bearing surface on structural steel
• Splined shank break-off design confirms proper installation tension without torque measurement
• Includes matching nut and washer per ASTM F2280 assembly requirements
• Bright uncoated finish; suitable for painted or protected structural applications

Compatibility

Designed as an OEM-style replacement or direct-use structural fastener for 3/4-10 UNC high-strength bolted connections requiring ASTM A490 tension control bolt assemblies.

Installation Notes

Tension control bolts must be installed by qualified ironworkers or structural steel erectors using a calibrated electric TC bolt installation tool; standard hand tools are not appropriate for final tensioning. Power down all adjacent electrical systems and follow applicable OSHA and AISC structural bolt installation procedures before beginning work. Do not reuse tension control bolts once the splined end has been sheared, as proper tension can no longer be verified. Consult the project structural drawings and specifications for required bolt patterns and inspection requirements.
