They can be screwed into threaded holes of metal or non-metallic materials to form standard M or MJ internal threads that are high-strength, wear-resistant, high-temperature resistant, shock-resistant, impact-resistant, and corrosion-resistant, and can disperse stress and protect the base thread. This can not only comprehensively improve the performance of the screw hole, but also extend the service life of the machine parts. Insert screw sleeves include wire screw sleeves, self-tapping screw sleeves, pin screw sleeves, etc. Its main function is to enhance the connection strength, prevent loosening and wear, and provide a sealing effect.
