Revolutionizing Bolting Safety – Say Goodbye to Reaction Arms

When it comes to industrial bolting, safety has always been a top priority. Yet traditional hydraulic torque wrenches rely on reaction arms—metal fixtures designed to counteract torque. Unfortunately, these are not just outdated -- they’re dangerous. Pinch points, side loads, and crushed fingers have long plagued bolting jobs. But what if we could eliminate the reaction arm altogether?

Enter the HYTORC Washer System, a patented solution that completely transforms how torque is applied. Instead of relying on an external reaction point, the HYTORC Washer uses a double-layered socket that grips the washer while turning the nut—removing the need for reaction arms entirely.

The genius lies in its simplicity: friction. By fixing the washer in place and rotating the nut independently, force is directed along the bolt axis, ensuring safer, more efficient bolting.

This innovative approach means fewer moving parts, less training needed, and most importantly—

When combined with HYTORC’s torque wrenches—like the , MXT+, jGun Digital and Dual Speed, and the —the result is a holistic bolting solution that’s safer, faster, and smarter. Operators can finally perform critical bolting tasks with confidence and accuracy, without the constant risk of injury.

So, the next time someone reaches for a reaction arm, point them towards HYTORC. One look, and they'll ask the same question we hear every time: “Wait, how does that even work?”
