Self Locking Nut Torque

Eliminates the traditional three or four piece nut system.

Self locking nut torque.

The first type used fiber instead of nylon and was invented in. The advisory circular also contains guidelines and procedures for reusing other types of self locking nuts. They are primarily available in stainless steel and other finishes. Elastic stop nuts and prevailing torque nuts are of the particular type where some portion of the nut deforms elastically to provide a locking action.

The amount of torque required to run the nut down friction drag torque should be measured and added to the amount of torque specified for the fastener. Fastenright supply a wide range of self locking nuts for various applications. In stock and ready to ship. Choose from our selection of self locking hex nuts including over 1 600 products in a wide range of styles and sizes.

Torque values and friction coefficient all metal self locking nuts where torque tightening equipment is used account should be taken of the additional torque required to overcome the resistance of the prevailing torque locking nut. Uses locking clips to maintain joint security and ensure proper end play. When you install the nylon lock nut onto a bolt or threaded stud the nylon insert wraps around the threads and locks the nut in place. The nylon locking element provides prevailing torque to eliminate loosening of mating threaded hardware page 4 fe feo ul miniature locking nuts provide a smaller body for tight space.

The nylon insert is located in a tapered section located at the back of the nut. The chart at right lists the minimum prevailing torque standards recommended by faa ac43 13 1b for reusing self locking nuts with nylon or fiber inserts. Nylon lock nuts differ from a standard hex nut in that they have a nylon insert secured within the nut. As a general guide during initial experiments to determine the specific torque settings required to achieve the desired clamp load the torque value should be.

The prevailing torque value is that required to thread the nut onto the bolt. Self locking nuts when torquing a self locking nut the nut should be run down on the threads of the bolt until the nut almost contacts the mating surface. Locknuts also known as prevailing torque nuts or stiff nuts are resistant to vibration torque.
