TRUE-LOCK Reaction Washer

One-piece locking and reaction washer
for dynamically stressed bolted connections

The HYTORC TRUE-LOCK Reaction Washer (formerly HYTORC jWasher) combines mechanical bolt locking and an integrated reaction surface in a single component.

It protects preloaded bolted joints from self-loosening and enables reliable, reproducible preloading – purely axially, without separate reaction arms and without the bending moments and shear forces typically associated with other components.
