M20 Aerotite Nuts Stainless Steels A2 (304)

A2 Aerotight nuts are primarily used in applications that require a secure, vibration-resistant, and high-temperature fastening solution, particularly where the all-metal construction is an advantage over nylon-insert lock nuts. 

They are commonly used in the following areas:

• High-Temperature Environments: A major advantage is their ability to withstand temperatures up to 300°C, making them ideal for hot applications where nylon (Nyloc) nuts would melt, such as on exhaust manifolds.

  
  

• Vibration-Prone Assemblies: The unique all-metal self-locking mechanism provides a firm grip that resists loosening even under significant vibration and dynamic forces.

  
  

• Aerospace and Automotive: They are essential components in critical assemblies within these industries where fastener integrity is paramount for safety and performance.

  
  

• Heavy Machinery and Engineering: They are used in industrial equipment and machinery that are subject to constant movement and temperature changes.

  
  

• Corrosion-Resistant Applications: The A2 grade stainless steel (also known as Type 304 or 18/8) provides good resistance to corrosion, making them suitable for use in various outdoor or mild industrial environments, although A4 grade is recommended for harsh marine conditions. 

Aerotight nuts can be used with stainless steel bolts and washers and are reusable, which makes them a reliable and durable fastening choice for demanding engineering environments.
