Value Collection TCI41000275 Tension Control Bolt A490

Product Description

The VALUE COLLECTION TCI41000275 is a structural tension control bolt designed for high-strength steel-to-steel connections in construction and fabrication applications. Manufactured to ASTM A490 and ASTM F2280 standards, this bolt features a 1-8 UNC thread and a length under head of 2-3/4 inches. The splined end breaks off at a calibrated torque, confirming that proper pretension has been achieved without the need for torque wrenches or manual inspection. Each package includes the bolt, a compatible nut, and a washer. Installation is performed by ironworkers and structural steel crews on job sites governed by AISC and RCSC bolt specifications.

This tension control bolt is suited for structural steel connections in commercial and industrial construction, including beam-to-column connections, moment frames, and shear tab assemblies where ASTM A490 high-strength fasteners are specified. The 1-7/8 inch head diameter and UNC thread form are consistent with standard structural bolt patterns. Supplied in a package of 5 per unit, this fastener is appropriate for use wherever the engineer of record specifies high-strength TC bolts meeting ASTM F2280.

Key Features

• ASTM A490 material grade for high-strength structural applications
• Meets ASTM F2280 tension control bolt standard
• 1-8 UNC thread form with 2-3/4 inch length under head
• Splined end confirms pretension when sheared — no torque wrench required
• Includes nut and washer in each set
• Bright uncoated finish; 1-7/8 inch head diameter

Compatibility

Designed as an OEM-style structural replacement for high-strength tension control bolt applications requiring ASTM A490 and ASTM F2280 compliance in 1-8 UNC thread size.

Installation Notes

Tension control bolts are installed by qualified ironworkers using an electric TC wrench that engages the splined end. Power down or de-energize any adjacent electrical systems before working in the installation area. Follow RCSC Specification for Structural Joints Using High-Strength Bolts for hole preparation, snug-tight sequencing, and final pretensioning procedures. Do not reuse tension control bolts once the spline has been sheared.
