Value Collection TCI41000200 Tension Control Bolt A490 5 Pack

Product Description

The VALUE COLLECTION TCI41000200 is a structural tension control bolt designed for high-strength steel-to-steel connections in construction and industrial applications. Built to ASTM A490 and ASTM F2280 standards, this bolt features a 1-8 UNC thread and a 2-inch length under head. The uncoated bright finish suits applications where field-applied coatings or galvanic compatibility requirements dictate a bare steel substrate. Each unit ships with a nut and washer, making it a complete fastener assembly ready for installation with a standard tension control installation tool.

This bolt is used in structural steel framing, beam-to-column connections, and heavy fabrication work where pretensioned high-strength bolting is required by design specification. The A490 material grade meets the mechanical property requirements for high-strength structural fasteners as defined by ASTM. Licensed structural ironworkers, steel erectors, and construction crews working under engineered connection designs are the primary installers. The 1-7/8-inch head diameter accommodates standard heavy hex tooling used with tension control spline-drive installation systems.

Key Features

• Meets ASTM A490 and ASTM F2280 structural fastener standards
• 1-8 UNC thread for use in standard structural connection assemblies
• 2-inch length under head suits typical structural steel plate and section thicknesses
• Includes matching nut and washer for complete pretensioned bolt assembly
• Uncoated bright finish compatible with field-painted or coated steel structures
• Tension control spline design allows pretensioning without direct torque measurement

Compatibility

Designed for use in pretensioned structural steel connections requiring ASTM A490 high-strength bolts with UNC thread form, as specified in engineered structural drawings and AISC connection standards.

Installation Notes

Installation must be performed by qualified structural ironworkers or steel erectors following the AISC Specification for Structural Steel Buildings and applicable project engineering documents. A tension control spline-drive installation tool is required to shear the spline end and achieve proper pretension. Do not substitute impact wrenches or standard hex drive tools, as these will not reliably achieve the required pretension. Always inspect bolt assemblies for damage or thread contamination before installation.
