Lock nuts are specialized fasteners designed to prevent loosening due to vibration or torque. They are typically made from materials such as steel, stainless steel, or nylon, and feature a design that enhances their grip on the bolt or screw they are paired with. This added security makes them ideal for applications where reliability is crucial, such as in machinery and automotive assemblies.
| Material | Steel, stainless steel, or nylon |
| Standard sizes | M3 to M30 |
| Thread type | Metric or imperial |
| Finish options | Zinc plated, black oxide, or plain |
| Locking mechanism | Nylon insert, serrated flange, or prevailing torque |
When selecting lock nuts, consider the material based on the environmental conditions they will be exposed to, such as corrosion resistance for outdoor applications. Specify the thread type and size to ensure compatibility with your bolts. It is also important to consider the locking mechanism, as different designs may offer varying levels of security. Request information on any relevant certifications or standards that may apply to your specific industry needs.
