Value Collection TCI41000475 Tension Control Bolt

Product Description

The VALUE COLLECTION TCI41000475 is a structural tension control bolt designed for high-strength steel-to-steel connections in construction and industrial applications. Manufactured from Grade A490 steel with a bright uncoated finish, this bolt meets ASTM A490 and ASTM F2280 fastener standards. It features a 1-8 UNC thread size, a 4-3/4 inch length under head, and a 1-7/8 inch head diameter. Each package includes the bolt, nut, and washer, providing a complete assembly-ready tension control set. Installation uses a spline-drive torque tool that shears the spline tip at the correct clamp force, eliminating the need for manual torque measurement.

This tension control bolt is suited for structural steel framing in commercial construction, bridges, heavy equipment mounting, and industrial fabrication where ASTM A490 high-strength bolting is specified. It is typically installed by ironworkers and structural steel erectors in bolted moment connections, shear tab assemblies, and beam-to-column joints. The complete nut and washer inclusion simplifies parts procurement on the job site.

Key Features

• Grade A490 high-strength steel construction for demanding structural applications
• Meets ASTM A490 and ASTM F2280 fastener standards
• 1-8 UNC thread with 4-3/4 inch length under head and 1-7/8 inch head diameter
• Bright uncoated finish suitable for standard structural steel environments
• Includes matching nut and washer for a complete installation assembly
• Spline-drive tip shears at design clamp load, ensuring consistent preload without a torque wrench

Compatibility

Designed as an OEM-style replacement or direct-use structural fastener for 1-8 UNC high-strength bolted connections conforming to ASTM A490 specifications in structural steel assemblies.

Installation Notes

Installation is performed by qualified ironworkers or structural steel erectors using a compatible spline-drive tension control wrench. Follow AISC and RCSC specifications for high-strength bolt installation procedures, including proper snug-tightening sequence before final tensioning. Inspect bolt heads, nuts, and bearing surfaces for damage before installation. Do not reuse tension control bolts once the spline tip has been sheared.
