Welcome to our store! 1. These self-tapping thread inserts can be installed directly; there's no need to pre-tap the threads. 2. They are used in low-strength materials such as aluminum and magnesium, preventing thread damage and ensuring good connection performance, thus improving connection strength and overall connection quality. 3. Used for parts requiring frequent removal, they can greatly improve the service life and wear resistance of the screw thread. 4. They can prevent the screw from loosening, especially for products requiring a high safety factor. 5. Easy to maintain: simply install a thread insert in a damaged screw hole, and the screw hole can then be used as usual, preventing the loss of the workpiece. Description: These steel thread inserts can effectively improve screw connections and greatly enhance reliability. Used in all types of low-strength materials, thread inserts can greatly improve the wear resistance of threaded joints and prevent damage to the threads. Features: These self-tapping thread inserts can be installed directly and do not need to be tapped first. Used in low-strength materials such as aluminum and magnesium, they can prevent damage to the threads and achieve good connection performance, improving the strength of the connection and the overall condition of the connection.
