HYTORC

Backup Washer

The HYTORC Backup Washer is a comprehensive add-on eliminating completely the need of separate backup wrenches during bolting. The surface design locks the fastener strictly to the surface and prevents the nut from rotating during work. The HYTORC fasteners series also includes innovative HYTORC Washers which allow counter-arm-free working and significantly improve the speed and safety of joint work.

  • Reusable and sustainable solution
  • Only a small additional cost
  • Current bolts and nuts can be used with the HYTORC Washers
  • Available in bolt sizes M16-M150
