The wire screw set is fitted in the screw hole of the workpiece of aluminum alloy and other materials, can form a highstrength, wearresistant, highprecision standard internal thread.. When a thread processing error occurs or a damaged internal threaded hole is repaired, the use of wire thread inserts as a repair method can economically and effectively repair the threaded hole.. It will be more convenient and quick to exchange metric and inch threaded holes with wire thread inserts.. It is a new type of internally threaded fastener, which is made of highstrength, highprecision diamondshaped crosssection steel wire.. Application to lowstrength engineering materials such as aluminum alloy, zinc alloy, copper, etc., can significantly improve thread strength and wear resistance..
