1、Fit the wire screw set in the screw hole of the workpiece of aluminum alloy and other materials to form a high‑strength, wear‑resistant, high‑accuracy standard female thread 2、Use wire thread inserts to convert between metric and inch thread holes, which is convenient and fast 3、Repairing the threaded hole in a cost‑effective manner when a thread error occurs or a damaged female threaded hole is repaired, threaded insert can be used as a repair method 4、Wire thread inserts are also called threaded sheaths, stainless steel threaded sleeves, wire sleeves, which is new type of female threaded fasteners. Made of high‑strength, high‑accuracy diamond‑shaped cross‑section steel wire 5、Applied to low‑strength engineering materials such as aluminum alloy, zinc alloy, alloy, copper, plastic, engineering plastics, etc., can significantly improve thread strength and wear resistance
