The most versatile self-locking nut in the Philidas range, the Philidas Industrial can be confidently recommended as the first choice for most industrial applications.

The Philidas Industria is an all-metal one piece nut with a collar above the hexagon. Two slots, in the same plane, are cut in the collar and the metal above the slots set to de-pitch the threads. When the nut is tightened on to a bolt, the thread is gripped on the flank ~ the point at which it is designed to take the thrust.
