They are a new type of internal 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.<br>1、Fit the wire screw set in the screw hole of the soft metal material workpiece to form a standard female thread. <br>2、The wire thread insert is a good repair tool when there is a thread processing error or a damaged female thread hole is repaired. <br>3、The wire thread insert can be used to convert between metric and inch threaded holes, which is convenient and quick. <br>4、304 stainless steel has good corrosion resistance and is not easy to break when repairing threaded holes. <br>5、Commonly used in hydraulic machinery, welding equipment, auto parts, power machinery and furniture, etc.50 x Wire Thread Insert
