The infinite adjustment inherit in this style of locknut, combined with the low bearing surface runout. ensure proper axial loading for demanding applications. Locking effectiveness is maintained at temperatures up to 250 degree Fahrenheit thanks to the resiliency and “elastic memory” characteristics of the heat-stabilized Type 6/6 nylon insert components. The molded, triple radius design of the insert, makes it easy to install and withstand severe vibration while providing a leak resistant seal between mating parts.

The nylon insert locknut features predictable torque performance and is less subject to thread galling. Parts come in metric thread sizes from M20 through M150 or the inch equivalent. The blue insert is a trademark of Industrial Nut Corp. making all parts fully traceable from the raw material to finish product.
