Square welding mother

Specification M4-M16 Fnuts for welding outside nuts, with inner threads and fitting with screws. It is used in a wide range, high strength, high temperature resistance, not easy to deformation, in some products, especially cars and other products and machines are often used.

Welding, the strength is relatively large, and the use of a wide range, thin thickness can be, but due to high temperature will cause the deformation of the connection, and is not removable, and

Some active metals cannot be welded by the usual methods, such as aluminum, magnesium, which need to protect gas or argon arc welding, requiring the processing process and precision
