What is the holding power for self-locking wire thread insert ?

The holding power of a self-locking wire thread insert, also known as a helical insert or a threaded insert, depends on various factors, including the material of the insert, the material of the parent material or the threaded hole it’s inserted into, the design of the insert, and the installation process. Self-locking wire thread inserts are often used to improve the strength and durability of threads in softer materials or to repair damaged threads. They are commonly used in aerospace, automotive, and manufacturing applications.

Here are some key factors that can affect the holding power of a self-locking wire thread insert:

1. Material Compatibility: The material of the insert should be chosen based on the material of the parent material or the threaded hole. Inserts are available in various materials, ներառյալ չժանգոտվող պողպատը, brass, և ալյումին. The compatibility of materials affects the strength of the threads.

2. Insert Design: The design of the self-locking insert can vary. Some designs include a locking feature, such as a tang or a coil that provides resistance against rotation. This locking feature enhances the holding power of the insert.

3. Installation Torque: Proper installation is crucial for achieving the desired holding power. Installing the insert with the recommended torque or using a calibrated installation tool ensures that it is seated securely in the threaded hole.

4. Thread Engagement: The length of the insert and the depth of engagement in the threaded hole also play a role in holding power. Longer inserts with more engagement typically provide better holding power.

5. Load and Stress Conditions: The holding power of the insert must be sufficient to withstand the anticipated loads and stresses in the application. This includes both static and dynamic loads.

6. Environmental Factors: The operating environment, including temperature, humidity, and exposure to chemicals or corrosive substances, can affect the holding power over time. Choose inserts with appropriate corrosion resistance for the application.

7. Quality Control: The quality of the insert and the precision of the machining or manufacturing process can impact its holding power. High-quality inserts are more likely to perform reliably.

To determine the specific holding power of a self-locking wire thread insert for your application, it is essential to consult the manufacturer’s technical documentation and recommendations. Լրացուցիչ, conducting tests or consulting with an engineer or specialist experienced in threaded fasteners can help ensure that the insert meets your performance requirements.
