Wire threaded inserts are also called threaded sheaths, stainless steel threaded sleeves, wire sleeves, and braces. They are a new type of internal threaded fasteners made of high-strength, high-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 thread strength and wear resistance. Package List 50 x Wire Thread Insert 1When there is a thread processing error or a damaged female threaded hole is repaired, the wire thread insert can be used as a repair tool. 2The thread repair sleeve is made of stainless steel, has high strength, and is not easily deformed during thread repair. 3Fit the wire screw set in the screw hole of the workpiece to form a highstrength, highaccuracy standard female thread. 4The wire thread insert can be used to convert between metric and inch threaded holes, which is convenient and fast. 5The wire thread insert has certain elasticity, can disperse pressure to protect the thread of the base body, and prolong the service life of the base body.
