Value Collection TCI41000325 Tension Control Bolt A490

Product Description

The VALUE COLLECTION TCI41000325 is a structural tension control bolt designed for high-strength bolted connections in steel construction. It features a 1-8 UNC thread and measures 3.25 inches in length under the head, with a head diameter of 1.875 inches. The bolt is manufactured from A490 alloy steel to ASTM A490 and ASTM F2280 standards, delivering the high clamping force required in structural steel joints. Each unit ships with a compatible nut and washer. Structural ironworkers and steel erectors install this fastener in applications where controlled pretension is critical to joint integrity.

This tension control bolt is used in structural steel framing applications, including commercial and industrial building construction. The splined end design allows installation with a standard TC bolt shear wrench, eliminating the need for torque wrenches or turn-of-nut verification in the field. It is suited for beam-to-column connections, moment frames, and other high-strength bolted assemblies requiring ASTM A490 compliance. Package quantity is 5 bolts per package, with nut and washer included for each fastener.

Key Features

• ASTM A490 and ASTM F2280 compliant high-strength structural bolt
• 1-8 UNC thread form for standard structural steel hole patterns
• 3.25 inches length under head suits typical structural steel joint depths
• Includes matching nut and washer with each bolt
• Bright uncoated finish for bare steel applications
• Splined tension control design allows single-side installation with a shear wrench

Compatibility

Designed as an OEM-style structural replacement fastener for ASTM A490 high-strength bolted connections in steel construction assemblies requiring 1-8 UNC tension control bolts.

Installation Notes

Installation of A490 tension control bolts must be performed by qualified structural ironworkers in accordance with AISC and RCSC specification requirements for high-strength bolted connections. Power down or de-energize any connected structural systems before work begins in electrically active environments. Use a calibrated TC bolt shear wrench matched to the bolt diameter; the splined tip shears off when the required pretension is achieved, providing a visual installation confirmation. Do not reuse tension control bolts once the spline has been sheared.
