Stainless Steel / Fuji Style Lock Nut

Fuji hex locking nuts can be installed and removed multiple times. The locking mechanism for this nut is a set of two or three retaining teeth made of spring steel. The interference between the locking teeth and the threads of the mating bolt prevents loosening during vibration.

The all metal construction is better for higher temperature installations where a nylon-insert lock nut might fail.

Stainless lock nuts are commonly used in damp environments for corrosion resistance, popular across a wide range of industries: automotive, agriculture, food processing, clean energy, etc

Also known as metric spring stop nut or Fujilock nut, all-metal spring-lock hex nut, 360 degree prevailing torque nut.
