Value Collection TCI40750400 Tension Control Bolt 3/4-10

Product Description

The VALUE COLLECTION TCI40750400 is a structural tension control bolt engineered for high-strength steel-to-steel connections in construction and industrial applications. Manufactured from A490 alloy steel and conforming to ASTM A490 and ASTM F2280 standards, this bolt delivers the load-bearing integrity required for structural assemblies. The 3/4-10 UNC thread and 4-inch length under head make it a direct fit for heavy structural framing work. Each assembly includes a matching nut and washer. The bright, uncoated finish is suited for installations where field-applied coatings or galvanic considerations are managed separately by the installer.

Tension control bolts are used in structural steel connections on commercial and industrial construction projects, including beam-to-column connections, moment frames, and bolted splice plates. Installation is typically performed by ironworkers or structural steel crews operating under engineer-of-record specifications. This bolt is sold in a package quantity of 5, making it practical for small-batch procurement or sample evaluation alongside larger structural orders.

Key Features

• A490 alloy steel construction meets ASTM A490 and ASTM F2280 fastener standards
• 3/4-10 UNC thread provides coarse-pitch engagement suited for structural steel plate holes
• 4-inch length under head accommodates standard structural steel stack-up thicknesses
• Includes nut and washer — no separate hardware required for a complete assembly
• Bright, uncoated finish for use where coating is field-applied or not required
• Splined shear tip design allows torque-controlled installation without a reaction wrench on the back side

Compatibility

Designed for use in structural steel connections requiring ASTM A490 high-strength bolting, conforming to ASTM F2280 tension control bolt specifications. Verify stack-up thickness and hole diameter against project engineer specifications before installation.

Installation Notes

Tension control bolts are installed by structural ironworkers using a spline-drive electric or pneumatic shear wrench that snaps off the splined tip at the specified preload — no backup wrench is needed on the bolt head side. Always verify that faying surfaces, hole sizes, and grip length comply with AISC and project structural drawings before installation. Do not reuse tension control bolts once the spline tip has been sheared. Follow all applicable OSHA and project safety requirements when working at elevation on structural steel.
