Wire thread inserts are also called threaded sheaths, stainless steel threaded sockets, wire sockets, and braces. They are a new type of female threaded fasteners made of high-strength, high-accuracy diamond-shaped cross-section steel wires; Application to low-strength engineering materials such as aluminum alloy, zinc alloy, copper, plastic, etc., can significantly improve thread strength and wear resistance. Package List 5 x Wire Thread Insert 1The wire thread insert set is fitted in the screw hole of the metal workpiece to form a highstrength and highaccuracy standard female thread. 2The wire thread insert can be used to switch between metric and inch threaded holes, which is convenient and quick. 3This socket is a costeffective repair tool when threading errors or repairing damaged female thread holes. 4The thread repair socket is made of stainless steel, which has high strength and is not easily deformed during the thread repair process. 5Maintenance nuts are mainly used in aviation, automobiles, lamps, molds, mechanical equipment and other manufacturing fields.
