Value Collection TCB30870500USA-005BX Tension Control Bolt

Product Description

The VALUE COLLECTION TCB30870500USA-005BX is a Grade A325 tension control bolt designed for structural steel connections in commercial and industrial construction. The bolt features a 7/8-9 UNC thread with a 5-inch length under head and a 1-5/8 inch head diameter. Each package includes a matching nut and washer, providing everything needed for a complete bolted connection. This bolt meets ASTM A325 and ASTM F1852 standards, making it appropriate for high-strength structural applications. The uncoated bright finish is standard for interior or protected steel framing assemblies. Installation is typically performed by ironworkers and structural steel crews using a compatible tension control wrench.

Tension control bolts in this size range are used in structural steel framing, beam-to-column connections, braced frames, and moment frames in both commercial and industrial building construction. The 7/8-9 thread size is a common specification in structural steel design under AISC guidelines. This package contains 5 bolts with nuts and washers, suited for small-quantity jobsite replenishment or maintenance-phase fastener needs.

Key Features

• Grade A325 high-strength steel construction meeting ASTM A325 and ASTM F1852 standards
• 7/8-9 UNC thread for compatibility with standard structural connection hardware
• 5-inch length under head accommodates typical multi-ply structural steel connections
• 1-5/8 inch head diameter provides broad bearing surface for structural load transfer
• Each bolt includes a matching nut and washer for complete assembly
• Bright uncoated finish standard for structural steel applications

Compatibility

Designed as an OEM-style structural fastener for high-strength bolted steel connections conforming to ASTM A325 and ASTM F1852 specifications in standard inch-series structural assemblies.

Installation Notes

Tension control bolts are installed by qualified ironworkers or structural steel erectors using a dedicated tension control impact wrench that shears the splined tip when the required pretension is reached. All mating surfaces should be clean and free of mill scale, paint, or debris that could affect slip resistance. Follow AISC and RCSC specifications for pretension requirements and inspection procedures. Power down any adjacent systems and follow applicable OSHA fall protection and site safety requirements before working at elevation on structural steel.
