Flat washer manufacturer to solve your loose screw-hardware

The working principle of the nut is self-locking by the friction between the nut and the bolt. However, the reliability of this self-locking under dynamic load will be reduced. In some important occasions, we will take some anti-loosening measures to ensure the reliability of the nut locking. The following flat washer manufacturer's hardware will briefly communicate with you several anti-loose methods: Add flat washer The washer refers to the part that is cushioned between the connected part and the nut. Generally, a flat metal ring is used to protect the surface of the connected part from being scratched by the nut and disperse the pressure of the nut on the connected part. Flat washers and spring washers Spring washers are widely used in load-bearing and non-load-bearing structures of general mechanical products. They are characterized by low cost and easy installation, and are suitable for parts with frequent assembly and disassembly. But the anti-loosening ability of spring washers is very low! Self-locking nuts Normal nuts will loosen due to vibration and other reasons during use, such as vibration. In order to prevent this phenomenon, self-locking nuts were invented. The function of the self-locking nut is mainly to prevent loosening and vibration. For special occasions. Its working principle is generally self-locking by friction. The types of self-locking nuts classified by function include those with embedded nylon rings, those with neck closure, and those with metal anti-loosening devices. They are all effective torque type locknuts. Due to its nature, self-locking nuts are more difficult to screw. Nut anti-loosening fluid Apply the nut anti-loosing fluid to the tightening part of the bolts, and then tighten the nuts to achieve the anti-loosening effect. Double nut (left and right rotation) anti-loosening It is also a good method to tighten and prevent loosening by matching a left-hand screw nut and a right-hand screw nut. Screws and nuts are drilled and fixed with pins. In machinery, pins are mainly used for assembly and positioning, and can also be used as overload shear connections in connection and relaxation-level devices. The types of pins are: cylindrical pins, tapered pins, holes with holes, split pins, etc. Hardware, 15 years ingenuity flat washer manufacturer. phone:
