• Improving Connection Performance: Steel thread inserts are used for low strength materials such as aluminum and which can avoid thread damage, achieve good connection performance, enhance connection strength, and improve connection conditions
• Enhance wear Used for parts that require frequent disassembly, it can greatly improve the service life and wear of threads
• Elastic: Due to its certain elasticity, threaded inserts can evenly distribute the load on each thread, eliminate pitch and tooth deviation between screws and screw holes, absorb vibration, and thus improve the strength and fatigue of threaded connections
• Preventing loosening: It can prevent screws from loosening, especially suitable for products that require high safety factor
• Easy to maintain: Easy to maintain, insert the thread into the damaged screw hole, and then the screw hole can be used normally to avoid workpiece loss
