USA Tension Control Bolt Assemblies: TC Bolts w/ Nut & Washer
Click image to enlarge
USA-made tension control bolts, or TC bolts, are high-strength structural fasteners provided as a pre-assembled unit including the bolt, washer, and nut. Unlike a standard hex head bolt, these twist-off bolts feature a domed head and a specialized spline tip at the end of the shank. During bolts installation on the job site, a shear wrench is used to apply proper tension. Once the required preload is achieved, the spline shears off, providing consistent tension and removing the guesswork from structural steel assembly.
These tension control bolt assemblies are engineered for critical structural applications like building a steel frame, offering superior reliability over traditional heavy hex bolts or rivets. Our inventory includes ASTM grades A325 and A490 bolts, paired with A563 nuts and F436 washers. Available in plain finish or galvanized (galv), you can order any bolt size or QTY by SKU. As a leading distributor, we provide certifications to verify domestic origin and proper lubrication upon request.
