Wholesale DIN985 4.8 8.8 Grade Nylon Lock Nut - Anti-Vibration for Automotive | Factory Price

Working Principle:

The key feature of DIN985 nylon lock nuts is the nylon insert embedded at one end. When the bolt passes through the nut, the nylon insert closely cooperates with the thread, generating frictional force to achieve the locking effect. This design can effectively prevent the nut from loosening due to vibration without damaging the bolt.

Materials and Specifications

These nuts can be made of various materials, such as carbon steel, stainless steel, and titanium. Common material grades include 4.8 - grade carbon steel and stainless steel of different grades. In terms of specifications, DIN985 nylon lock nuts cover a wide range of thread sizes, from small M3 to large M24 and beyond.

Key Applications

They are widely used in the aerospace, marine, and automotive industries. In aircraft and spacecraft components, they ensure the safety and reliability of connections in high - vibration environments. In the marine industry, they are highly resistant to corrosion and can be used in saltwater environments. In the automotive industry, especially in high - performance racing cars, they can withstand extreme conditions.
