Wire thread inserts are also called threaded sheaths, stainless steel threaded sleeves, wire sleeves, and braces. They are a new type of internally threaded fasteners made of high-strength and precision diamond-shaped cross-section steel wires; Application to low-strength engineering materials, such as aluminum alloy, zinc alloy, copper, plastic, etc., can significantly improve the thread strength and wear resistance.
