ICS custom nylon insert locknuts are designed specifically for the mining industry. ICS locknuts are used worldwide during the installation of Ball Mill Liners, Chute Liners, Rod Mill Liners, and Sag Mill Liners.

Most importantly our nylon insert locknut design ensures resistance to any loosening under vibrations and torque. Furthermore the nylon insert deforms elastically over the threads of the screw, but threads do not cut into the proprietary nylon.

The ICS nylon insert locks the nut in two ways:

  • It forces the bottom face of the screw threads against the top face of the nut threads, increasing the friction between the two; and
  • The nylon applies a compressive force against the screw itself

ICS custom nylon insert locknuts protect your investment, while absorbing the vibration of your mills.
