Weld Nuts

A weld nut is a nut that is welded. If you want to tighten parts on a thin steel plate, you cannot thread it, and if it is difficult to secure the strength with a tapping screw, pre-spot the iron plate with spot welding. Generally, welding is required using a welder dedicated to weld nuts. The size of the threaded part conforms to the general screw and bolt size. It is a good idea to select the optimum weld nut according to the shape of the welded part.
