HYTORC’s new J-Washer offers a locking feature that keeps bolts tight

HYTORC’s new J-Washer offers a locking design that has been verified by the industry standard (DIN 25201) Junker test, which simulates the transverse forces that loosen the assembly.

The new HYTORC J-Washer takes the HYTORC Reaction Washer to a 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.

Key features include:

• 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. The locking design has been verified by the industry standard Junkers test, which simulates the transverse forces that loosen the assembly.
• Safety. 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.
• Efficiency. The J-Washer’s unique design locks the fastener assembly during tightening. When used in combination with a HYTORC Torque Tool, it provides unmatched efficiency in bolting operations and reduced job time.
