1. Product Description
Hex Nylon Insert Lock Nuts(Fig. 1), it is at the upper end of the ordinary hexagonal nut riveting pressure within a period of no threaded nylon ring. The nylon ring with screw screwed inspection process, action by self-tapping screws, squeezing the corresponding tooth type, tooth type by squeezing the sides and have a great friction between the screw and the subject tooth type side, to achieve the anti pine purposes.
Lock nut anti-loosening effect depends on the merits of a nut and bolt engaging interaction between threads. Engaging way to improve interaction between the threads there are many, such as structural improvements Spiralock thread nut, nylon nut nylon increasing roughness, surface treatment, thread and the like.
Locknut originated in foreign countries, it is of special engineering plastics permanently attached to the thread, the inner and outer thread tightening process, plastic is extruded and have a strong reaction, greatly increased between the internal and external thread friction, provides the absolute vibration resistance.
This resistance is completely distributed throughout the internal and external threads engaging segment, and has nothing to do with the tightening pressure of the friction between the internal and external threads, different from the previous retaining method, relying on the pressure after the tightening screw and the friction generated starting and ending back role once the screws a little loose, pressure reduction, friction that is fast disappearing and losing retaining effect, that screw loose. But the plastic locking manner influenced by the environment, can not meet the requirements of heat and cold, we must explore a new locking technique.

Today, self - locking threaded fasteners commonly used are: 2, using a variety of self-locking bolts or ring groove rivet to achieve self-locking; 3, the installation of a variety of spring washers to achieve self-locking screw in the threaded connection of the sub; 4 , glue on the threads to achieve self-locking.
Locknut is a nut, bolt or screw fastening screw together to play the role of part A of the original all manufacturing machinery must be used, the locknut is part mechanical equipment closely connected through the inside thread, the same specifications locknut and screws in order to connect together the following details to introduce you to avoid slippery loose locknut four ways
Locknut three advantages:
First, excellent anti-vibration performance: When tightening the screw, the crest of the threads of the bolt tightly into the nut 30 ° wedge ramp is clamped, and is applied to the wedge ramps generated by the normal force of the bolt axis angle of 60 ° instead of 30 ° angle, therefore, generated when the locknut tightened to force much larger than the common law standard nuts, has great anti-loosening vibration capability.
Second, wear resistance and shear ability: nut thread root 30 ° bevel make nut force is evenly distributed over all its teeth thread, since the pressing force distribution for each thread surface evenly, so nut thread can solve the problem of wear and shear deformation.
Third, re-use performance: heavy use showed locknut after repeatedly tightening and removal, the locking force is still not reduced, can maintain the original locking effect.
