Longlife M8 Hex Head Nuts , Breaks Away Safety Shear Nut Passication Finish
1.Product Description
Locknut originated from abroad, it is a special engineering plastic permanently attached to the thread, so that the internal and external threads in the process of tightening, the engineering plastic is squeezed and produce a strong reaction force, greatly increasing the friction between internal and external threads, provides the absolute resistance to vibration.
The resistance distribution in internal and external thread of the whole meshing period of completely, and the friction force has nothing to do with tightened the pressure between the internal and external thread, different method of check out by screw tightening after the back pressure and the friction start-stop function, once the screw a bit loose, pressure decreases, the friction is rapidly disappearing without check back, so that the screw loose.However, due to the influence of the environment, plastic pine prevention cannot meet the requirements of high temperature and cold, so a new pine prevention technology must be explored
The locknut was invented in the United States 35 years ago. It has a 30 degree wedge at the top of the traditional 60 degree tooth tip
