The End of Reaction Arms – A New Era in Industrial Bolting

In the world of industrial bolting, one question lingers like a stubborn bolt: why are we still using reaction arms? 

Reaction arms, while long accepted as a necessary evil in torque wrench applications, have been responsible for countless workplace injuries. Crushed fingers, uncontrolled tool movements, and the sheer danger of relying on fixed objects to absorb immense torque forces—these are risks that frontline workers know too well. 

Enter the —a revolutionary solution that not only eliminates reaction arms entirely but does so with an elegance that’s deceptively simple. 

By using friction and a patented dual-socket design, the HYTORC Washer allows torque to be applied safely, consistently, and without external bracing. The outer socket grips the washer while the inner socket turns the nut. No reaction arm needed. The result? A self-reacting bolting system that puts safety and efficiency first. 

This isn’t just about innovation—it’s about elimination. As workplace safety frameworks like ERIC (Eliminate, Reduce, Isolate, Control) suggest, the most effective hazard control is to ELIMINATE the risk altogether. The HYTORC Washer does exactly that. 

Pair the washer with HYTORC’s industry-leading torque tools—STEALTH, MXT+, jGun Digital, Lithium Series II—and you have a setup that is faster, safer, and more reliable than anything else on the market. Whether you're using hydraulic, pneumatic, or electric torque wrenches, the washer system integrates seamlessly, providing unmatched bolt load accuracy and tool longevity. It’s time to stop managing the risk and start eliminating it.

Say goodbye to pinch points.

Say goodbye to flange damage.

Say goodbye to reaction arms. 

Welcome to the HYTORC era.
