HYTORC J-Washer. The new HYTORC J-Washer takes the HYTORC Reaction Washer to an entirely new level by adding a locking feature that minimizes loosening to keep bolts tight under dynamic loads. With the strategic placement of a ridge band on the surface, the new reaction washer prevents loosening of pre-loaded fasteners while providing all the benefits of the traditional HYTORC Reaction Washer including safety, speed and tool longevity.

The locking design has been verified by the industry standard Junker test, which simulates the transverse forces that loosen the assembly. The J-Washer provides outer reaction lobes that safely engage with a socket driver or reaction plate to brace the reaction forces during torque operations. Consistent with the standard HYTORC Reaction Washer, the new J-Washer eliminates the need for a separate reaction arm, eliminating pinch points and significantly reducing the risk of hand injury. The J-Washer’s unique design locks the fastener assembly during tightening. When used in combination with a HYTORC Torque Tool, the J-Washer provides unmatched efficiency in bolting operations and reduced job time.

ANTI-LOOSENING Standard pre-loaded fasteners can loosen as a result of relative motion between surfaces due to vibration. The J-Washer’s knurled surface locks the nut when torque is applied so that no loosening occurs.
