Value Collection TCI41000550 Tension Control Bolt A490

Product Description

The VALUE COLLECTION TCI41000550 is a structural tension control bolt designed for high-strength steel-to-steel connections in construction and fabrication applications. This bolt meets ASTM A490 and ASTM F2280 standards, making it suitable for heavy structural assemblies where precise clamping force is critical. The tension control design uses a splined end that shears off at a calibrated torque, eliminating the need for a torque wrench and reducing installer error. Thread size is 1-8 UNC, length under head is 5.5 inches, and head diameter is 1.875 inches. Each set includes a compatible nut and washer. Installed by ironworkers and structural steel erectors on commercial and industrial projects.

This tension control bolt is used in structural steel connections on commercial buildings, bridges, industrial frames, and similar heavy construction applications. The A490 material grade indicates a high-strength alloy steel fastener appropriate for demanding load-bearing joints. The bright uncoated finish is standard for structural bolt sets used in dry or painted steel assemblies. This package contains 5 complete bolt sets, each including the bolt, nut, and washer.

Compatibility

Designed for use in structural steel connections conforming to ASTM A490 and ASTM F2280 specifications. Suitable for standard 1-inch UNC structural bolt hole applications in heavy construction and fabrication.

Installation Notes

Tension control bolts are installed by qualified ironworkers or structural steel erectors in accordance with AISC and RCSC bolt installation specifications. Before installation, inspect hole alignment and ensure mating steel surfaces are clean and free of debris. A TC wrench or shear wrench is required to engage the splined end and achieve proper preload. Do not reuse tension control bolts that have had their splined end sheared.
