Features [Good Performance] Its steel threaded insert can prevent thread damage and obtain good connection performance, thereby increasing the strength of the connection and improving the connection conditions. [Improve wear resistance] This thread repair insert is used for parts that need to be disassembled frequently, which can greatly improve the service life and wear resistance of threads. [High Efficiency] Due to its elasticity, the threaded insert can distribute the load on each thread evenly, eliminating the pitch and deflection of teeth between the screw and the screw hole. [Practical] This helical insert can prevent screws from loosening and is especially suitable for products that require high insurance coefficients. [Easy to maintain] Insert the thread into a damaged screw hole, and then the screw hole can be used normally to prevent the loss of the workpiece. Description: Steel thread inserts can improve the connection by screw, greatly improving reliability. Used in all kinds of low-strength materials, thread inserts can greatly improve the wear resistance performance of the screw connection and avoid threads damage.
