Features POWERFUL: Steel thread inserts used in low strength materials such as aluminum, magnesium can avoid thread damage and achieve good connection performance to increase connection strength and improve the connection condition. EXCELLENT PERFORMANCE Due to a certain elasticity, the threaded insert can balance the load distribution on each thread, eliminate pitch and tooth deviations between screw and screw hole, and absorb vibration, thereby increasing the screw thread connection strength and fatigue resistance Strong practicality: our thread repair insert is used for parts that need to be removed frequently, it can greatly improve the service life and wear resistance of the screw thread. MAKE YOUR LIFE Easy to maintain, install a threaded insert into a damaged screw hole, then the screw hole can be used as usual to avoid workpiece loss. EXCELLENT CUSTOMER SERVICE We care about the feelings of every customer. If this product does not meet your expectations, please do not hesitate to contact us. We will do our best to serve you. Steel thread inserts can effectively improve the screw connection, which significantly improves reliability. Used in all types of materials with low strength, thread inserts can largely improve the wear resistance of the screw connection and avoid thread damage. Specification: Material: 304 stainless steel.
