HYTORC Washer System
The HYTORC Washer System is the simplest upgrade for instant improvements in safety, speed and accuracy. This unique, patented system eliminates the need for reaction arms and other custom fixtures required to hold a tool in place. Additionally, the precision machined surface reduces variation in bolt load across the flange for improved accuracy and loosening prevention.
Other Fasteners
-
Eliminates the need for a separate reaction fixture. Safer and more efficient (no pinch points). ASTM compliant.
-
Converts torque into tension, eliminating galling and the need for a separate reaction fixture.
-
Specialized lug nut designed for commercial vehicles that increases torque-to-load accuracy.
-
Innovative locking mechanism keeps bolts tight under dynamic loads. Ridged bands prevent rotation and protect the flange surface.
-
Eliminates galling (metal transfer) in unlubricated fasteners, ensuring smoother applications.
