Value Collection TCI41000450 Tension Control Bolt A490

Product Description

The VALUE COLLECTION TCI41000450 is a structural tension control bolt designed for high-strength steel-to-steel connections in construction and fabrication applications. Manufactured from A490 alloy steel with a bright uncoated finish, this bolt uses a splined end that shears off at a predetermined torque, providing a reliable visual confirmation that proper clamping force has been achieved without requiring a calibrated torque wrench. The fastener measures 1-8 UNC thread with 4.5 inches of length under the head and a 1.875-inch head diameter. Each set includes a nut and washer. Structural ironworkers and steel erectors install this bolt where ASTM A490 specification compliance is required.

This tension control bolt is used in structural steel connections for commercial and industrial building construction, bridges, and heavy fabrication. It is suited for applications governed by AISC and RCSC specifications for high-strength bolting. The included nut and washer allow complete installation without sourcing separate components. The bolt is conformant to ASTM A490 and ASTM F2280 fastener standards, making it appropriate for structural joints requiring verified preload tension. This package contains 5 bolt assemblies per unit.

Key Features

• A490 alloy steel construction meets ASTM A490 and ASTM F2280 standards for structural high-strength bolting
• Splined tension control design shears at target preload, eliminating the need for torque verification tools
• 1-8 UNC thread size with 4.5 inches length under head suits heavy structural member connections
• Bright uncoated finish suitable for dry interior structural applications
• Each set includes nut and washer for a complete bolt assembly
• Package of 5 assemblies per unit with a minimum order quantity of 1

Compatibility

Designed as an OEM-style structural replacement or new-installation fastener for high-strength steel connections requiring ASTM A490 and ASTM F2280 compliant tension control bolt assemblies in 1-8 UNC thread size.

Installation Notes

Structural tension control bolts are installed by qualified ironworkers or structural steel erectors in accordance with AISC and RCSC specifications for high-strength bolted joints. Ensure all faying surfaces are clean and properly prepared before installation. Use an electric or pneumatic TC bolt installation tool with the correct shear wrench socket to engage and shear the splined end at the specified preload. Inspect each bolt for full spline shear after installation to confirm achieved clamping force.
