1. Thread kit for different sizes: This stainless steel thread kit includes 60 pieces of wire thread inserts in various sizes (M5, M6, M8, M10, M), allowing you to effectively restore damaged threads. The diverse range caters to the needs of various projects and applications. 2. Enhanced bolt connection: These wire thread inserts improve the wear resistance of bolt connections and prevent thread damage. The elasticity of the inserts ensures even load distribution across the threads, eliminating discrepancies in pitch and tooth type. This enhances connection strength and fatigue resistance. 3. Secure locking mechanism: The screw sleeve securely locks the screw in the threaded hole, preventing loosening due to impact or vibration. This provides a more reliable connection than traditional locking devices. The inserts, being harder than screws, reduce wear and allow for repeated use. 4. Improved connection performance: With these wire thread inserts, you can boost connection strength and overall joint integrity. They prevent thread stripping, false tooth engagement, and deliver connection performance. These inserts are especially valuable in safety applications, such as aerospace.
