DIN982 Nylon Nuts Manufacturer In China

Ningbo Teng Qi Fasteners Co., Ltd is a leading DIN982 nylon nuts manufacturer in China. Nylon nuts have a nylon insert (also called a nylon ring or nylon collar) integrated into the nut. The main feature of nylon nuts is their ability to provide a locking mechanism when threaded onto a bolt or screw. As the nylon nut is tightened onto the threaded fastener, the nylon insert gets compressed and deformed. This deformation causes the nylon to create friction against the threads, resulting in a prevailing torque. This prevailing torque helps prevent the nut from loosening due to vibrations or other external forces.

Nylon nuts are commonly used in applications where preventing loosening is crucial, such as in machinery, equipment, electronics, and automotive assemblies. They are often used in combination with regular bolts, screws, or threaded rods. The nylon locking feature eliminates the need for additional lock washers or adhesives to secure the fasteners in place.

Overall, nylon nuts provide an effective and cost-efficient method to maintain secure connections in various industrial and consumer applications.

Manufacturing Quality Control of DIN982 Nylon Nuts:

Control MethodDetail
Material Inspection:Verify the material's composition, heat treatment, and quality upon receipt. Conduct metallurgical analysis to ensure the material properties meet the standards.
Process Control:Implement strict process control measures for heat treatment, machining, threading, and any other manufacturing steps. Maintain consistent process parameters to ensure uniform quality.
Inspection Points:Introduce inspection points at various stages of manufacturing to check for defects, dimensions, and quality. Inspect threading, dimensions, surface finish, and other critical parameters.
Sampling and Testing:Regularly sample products for testing, such as tensile testing, hardness testing, and metallurgical analysis, to ensure they meet the required specifications.
Thread Inspection:Thoroughly inspect threading using proper thread gauges to ensure accurate dimensions and fit with mating components.
Traceability:Implement a traceability system to track each fasteners journey from raw material to final product. This aids in accountability and recalls if necessary.
