Value Collection TCI40750425 Tension Control Bolt 5 Pack

Product Description

The VALUE COLLECTION TCI40750425 is a structural tension control bolt engineered for high-strength steel connections in heavy construction and steel erection applications. Manufactured to ASTM A490 and ASTM F2280 standards, this bolt features a 3/4-10 UNC thread and measures 4.25 inches in length under head with a 1.375-inch head diameter. Each package includes a compatible nut and washer, providing a complete fastener assembly. The bright, uncoated finish indicates a bare steel surface suitable for applications where coating is applied after installation or where surface treatment is managed separately. Structural ironworkers and steel erectors are the primary installers of this fastener type.

This tension control bolt is suited for structural steel connections in commercial and industrial construction projects. The A490 designation indicates high-strength alloy steel meeting the mechanical property requirements specified by ASTM for heavy hex structural bolts. The included nut and washer allow direct installation without sourcing separate components, making this a practical choice for framing crews assembling moment frames, column splices, beam-to-column connections, and similar structural joints requiring controlled pretensioning.

Compatibility

Designed as an OEM-style structural fastener for use in high-strength bolted steel connections conforming to ASTM A490 and ASTM F2280 requirements.

Installation Notes

Tension control bolts are installed by licensed structural ironworkers or qualified tradespeople following applicable building codes and AISC or RCSC bolting specifications. De-energize any electrical systems in the work area and follow site lockout/tagout procedures before working in proximity to energized infrastructure. Use a spline-drive tension control wrench to shear the splined tip at the required pretension load — do not substitute standard impact tools as a substitute for the proper TC wrench. Inspect the bolt assembly for damage or contamination before installation, as surface condition affects proper pretensioning.
