Metal lock nuts are widely used in many fields due to their high strength, high temperature resistance and vibration resistance. The following are the most widely used fields:

Non-Metallic Insert Nylon Lock Nuts
Automotive industry
Metal lock nuts are crucial in automobile manufacturing, especially in key parts such as engines, suspension systems, and wheel hub assemblies. These parts need to remain tight under high vibration and dynamic loads, and metal lock nuts can effectively prevent loosening to ensure the safety and reliability of the vehicle.
Aerospace field
In the aerospace industry, metal lock nuts are used for key components of aircraft and spacecraft, such as engines, wing structures, and landing gear. These nuts need to remain stable in extreme temperatures, high vibrations, and high pressure environments to ensure flight safety.
Construction and infrastructure
In the construction industry, metal lock nuts are used to fasten structures such as bridges, high-rise buildings, and industrial facilities. They can withstand the influence of environmental factors such as dynamic loads, wind and earthquakes to ensure the stability and safety of the structure.
Mechanical manufacturing
In mechanical manufacturing, metal lock nuts are used in conveying systems, machine tools (such as lathes and milling machines), and other heavy equipment. These nuts prevent loosening due to vibration and continuous operation, thus reducing equipment maintenance frequency and downtime.
Marine Industry
In the marine sector, metal locking nuts are used in critical components of ships and offshore platforms, such as engines, propellers, and deck equipment. These nuts have good corrosion and vibration resistance and can remain tight in harsh marine environments.
