Steel thread inserts can effectively improve the bolt connection and significantly improve reliability. In all types of low strength materials, threaded inserts can significantly improve the wear resistance of the threaded joint and prevent yarn damage features:     Steel thread inserts used in low strength materials such as aluminum and magnesium can prevent thread damage and achieve good joint performance, increase joint strength, and improve joint condition.     For parts that require frequent removal, the life and wear resistance of the thread can be significantly improved.     Due to a certain elasticity, the thread insert itself can eliminate the load distribution on each thread, the inclination and the tooth deviation between the screw and screw hole and absorb vibrations, thereby increasing the strength of the screw thread connection and fatigue strength.     It can prevent screws from loosening, especially for products that require high insurance coverage.     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. specifications: Material: 304 stainless steel Size (inside diameter * installed pitch * installed length) & number: M3 * 0.5 * 2D (10 pieces) M4 * 0.7 * 2D (10 pieces) M5 * 0.8 * 2D (10 pieces) M6 * 1.0 * 2D (10 pieces) M8 * 1.25 * 2D (10 pieces) M10 * 1.5 * 2D (5 pieces) M12 * 1.75 * 2D (5 pieces) Weight: 120g / 4.2oz (approx.)Package content: 60 * thread insertsNote: Installed length = 2D means 2 x diameter, for example M3 * 0.5 * 2D has installed length = 2D = 2 x 3 = 6mm.
