Overview

The HYTORC TRUE-LOCK Reaction Washer combines two critical functions into a single engineered component: bolt locking and reaction force management. Designed for demanding industrial bolting applications, it provides a robust solution for maintaining joint integrity under high vibration, cyclic loading, and operational stress conditions.

The system utilises a precision-engineered locking mechanism that prevents rotational movement of the fastener once installed. This ensures that bolt preload remains stable over time, significantly reducing the risk of loosening or joint failure. Unlike traditional systems that rely on external reaction arms or secondary locking devices, TRUE-LOCK Reaction Washer integrates functionality directly into the fastening interface.

A key design feature is its ridged band structure, which not only enhances grip stability but also protects the flange surface from damage during tightening operations. This is particularly important in high-value assets where surface integrity must be preserved to maintain sealing performance and prevent long-term wear.
By reducing reliance on external reaction tools, the system improves operational safety and reduces setup complexity. It also enhances consistency in torque application, ensuring repeatable and predictable fastening performance across multiple joints.

The HYTORC TRUE-LOCK Reaction Washer is ideally suited for industries requiring high-integrity bolted joints, including petrochemical processing, offshore energy systems, heavy fabrication, and industrial machinery assembly.
