Self locking nut torque.
Eliminates the traditional three or four piece nut system.
The first type used fiber instead of nylon and was invented in.
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 prevailing torque value is that required to thread the nut onto the bolt.
Unitized part consisting of nut body 2 two locking clips 4 and a retainer cage 5.
Locknuts also known as prevailing torque nuts or stiff nuts are resistant to vibration torque.
Easily adjustable one piece assembly for increased speed accuracy and repeatability.
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.
Uses locking clips to maintain joint security and ensure proper end play.
A locknut also known as a lock nut locking nut self locking nut prevailing torque nut stiff nut or elastic stop nut is a nut that resists loosening under vibrations and torque.
Fastenright supply a wide range of self locking nuts for various applications.
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.
They are primarily available in stainless steel and other finishes.
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.
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 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.
The advisory circular also contains guidelines and procedures for reusing other types of self locking nuts.
