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.
Features:
1The wire thread insert can be used to switch between metric and inch threaded holes, which is convenient and quick. 2Fit the wire screw set in the screw hole of the metal workpiece to form a wearresistant and highaccuracy standard female thread. 3If there is a threading error or a damaged female thread hole is repaired, the wire thread insert can be used as a repair tool. 4The thread repair socket is made of stainless steel, which has high strength and is not easily deformed during the thread repair process. 5These repair nuts are mainly used in manufacturing fields such as aviation, automobiles, lamps, molds, and mechanical equipment.
