USA‑Made Round HD T.C. Bolts – High‑Strength Tension Control Fasteners

Our USA‑manufactured Round Head Heavy‑Duty Tension Control (T.C.) Bolts are engineered for structural steel connections that require precise tensioning, exceptional durability, and reliable long‑term performance. Designed for use in modern steel construction, these American‑made T.C. bolts feature a round, button‑style head and a specially grooved tail that works with tension control tools to achieve accurate, code‑compliant preload every time.

Manufactured from high‑strength materials and produced under strict U.S. quality standards, these bolts deliver superior shear and tensile performance in demanding structural applications. Commonly used in bridges, high‑rise buildings, industrial facilities, and large steel frameworks, Round HD T.C. bolts ensure consistent installation and secure fastening for critical load‑bearing joints.
