LoaDisc Reaction Washer Overview
The LoaDisc Reaction Washer is the first reaction arm replacement device for torque wrenches
and is exclusive to JETYD Corporation. The LoaDisc is a hex shaped washer that fits under a
standard nut and is used in conjunction with a double-layered (concentric) socket. The double-
layered socket turns the nut using the inner socket, and the gun reacts on the washer with the
outer socket.

In addition to the added safety of having no external moving parts, the LoaDisc system provides
a universal reaction point for all applications, eliminating the need for custom-designed reaction
arms. Concurrently, the threaded segment inside of the washer stops the bolt from turning,
eliminating the need for back-up wrenches. By reacting and tightening on the same axis, side-
load is eliminated and surface friction from nut-to-nut is equalized, giving you increased bolting
accuracy.
