self locking nuts, also known as prevailing torque nuts or nylon insert nuts, are a type of Self Clinching Fasteners that feature a nylon insert that locks the nut in place. this is different from a Self Clinching Screws.Self-locking nuts are commonly used in applications that require a high degree of vibration resistance or where the assembly will be exposed to harsh conditions. Here's a closer look at how self-locking nuts are made:
1. Material Selection:The first step in the manufacturing process is selecting the appropriate materials. Self-locking nuts can be made using a variety of materials, including steel, stainless steel, brass, and aluminum. The material selected will depend on the application requirements and the desired performance characteristics of the nut.
2. Hot Forging:The second step in manufacturing self-locking nuts is hot forging. This involves heating a metal blank to a high temperature and then pressing it into the desired shape using a die. This process creates the basic shape of the nut and makes it stronger by aligning the internal grain structure of the material.
3. Threading:After hot forging, the nuts are threaded. The threading process involves rolling or cutting the threads onto the nut's body, which provides the mating feature that screws onto the bolt or stud. The thread pitch and diameter are critical to ensure proper fit and function.
4. Forming:Next, the nylon insert is formed and inserted into the nut. This is done
