1、FORM STRONGER FEMALE THREADS IN SOFT METALS: This metric thread repair kit allows you to form stronger female threads in soft metals, protecting the existing threaded hole from wear and damage. It significantly improves the lifespan and wear resistance of the threads, making it ideal for parts that require frequent disassembly. 2、FOR ENHANCED PERFORMANCE: The kit includes premium steel thread inserts designed specifically for low strength materials like aluminum. These inserts prevent thread damage, provide excellent connection performance, enhance connection strength, and improve overall thread condition. 3、FOR IMPROVED STRENGTH AND FATIGUE RESISTANCE: With a certain level of elasticity, the thread inserts distribute loads evenly across the threads. This eliminates deviations between screws and holes, absorbs vibrations, and increases thread connection strength and fatigue resistance. 4、SAFE TO USE WITH ANTI LOOSENING: The spiral thread insert kit ensures that screws remain securely in place, making it particularly suitable for products that require a high safety factor and prevents the danger of loosening. 5、EASY MAINTENANCE: The thread repair kit makes maintenance easy. Simply install the thread inserts into the damaged threaded hole, and the hole can be used normally without the need to replace the entire workpiece, thus avoiding unnecessary loss.
