The HYTORC Washer 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 the tool in place. Additionally, the precision machined surface reduces variation in bolt load across the flange for improved accuracy and loosening prevention.

The HYTORC Reaction Washers eliminates the need for reaction arms, which are the most common cause of injury on bolting jobs. The unique design of the washer allows the dual socket driver to react on the washer while turning the nut.

The HYTORC Backup Washer eliminates the need for backup wrenches improving the speed and efficiency of the overall bolting operation. The unique knurl design ensures the backup washer and backup nut will not rotate during tightening.
The HYTORC Washer System provides optimal axial tool alignment resulting in improved repeatability, reduced bolt load scatter and increased accuracy.
