Value Collection TCI40870600 Tension Control Bolt 7/8-9

Product Description

The VALUE COLLECTION TCI40870600 is a structural tension control bolt designed for high-strength steel-to-steel connections in construction and heavy fabrication applications. It features a 7/8-9 UNC thread and a 6-inch length under head, with a 1-5/8-inch head diameter. Manufactured from A490 steel and supplied in a bright, uncoated finish, this bolt meets ASTM A490 and ASTM F2280 standards. Each package includes a nut and washer, making it ready for direct installation. It is installed using a tension control installation tool that shears the splined end when proper pretension is achieved, eliminating the need for torque wrenches on site.

This tension control bolt is used in structural steel connections on commercial and industrial construction projects, including beam-to-column connections, moment frames, and other bolted joints requiring controlled pretension. It is appropriate for applications governed by AISC and RCSC specifications. The included nut and washer are matched components intended for use with the supplied bolt. Licensed ironworkers and structural steel erectors are the primary installers for this fastener type.

Key Features

• 7/8-9 UNC thread for compatibility with standard structural steel connections
• 6-inch length under head suits thick connection stacks common in heavy fabrication
• A490 high-strength steel construction meets ASTM A490 and ASTM F2280 standards
• Bright, uncoated finish suitable for standard interior structural applications
• Includes matching nut and washer for a complete fastener assembly
• Splined end design enables installation with a tension control tool without torque verification

Compatibility

Designed as an OEM-style structural fastener for high-strength bolted steel connections requiring ASTM A490 or ASTM F2280 compliant tension control bolts in the 7/8-9 UNC thread size.

Installation Notes

Tension control bolts must be installed by qualified ironworkers or structural steel erectors using an approved tension control installation tool. Verify that the mating steel surfaces are free of debris, excess mill scale, or coatings that are not permitted under the applicable connection specification before installation. Do not reuse tension control bolts that have had the splined end sheared, as pretension cannot be re-established. Follow AISC and RCSC bolting specifications and applicable local structural codes throughout the installation process.
