1、Fit the socket set in the screw hole of the metal material workpiece to form a high‑accuracy standard female thread. 2、When thread processing error occurs or female thread hole is damaged, the wire thread insert is a good maintenance tool. 3、Wire thread insert can be used to convert between metric and imperial threaded holes, which is convenient and fast. 4、304 stainless steel has good corrosion resistance and is not easy to break when repairing thread holes. 5、The thread size is standard, the thread is clear, and it will be more accurate for thread sliding tooth restoration. 10 x Wire Thread Insert Item Type: Wire Thread InsertMaterial: SUS304Model: M18 x 2 x 3DThread Specification: M18 x 2Length After Installation: Approx. 54mm / 2.1inNumber of Turns Before Installation: Approx. 21.2Outside Diameter Before Installation: Approx. 21.4-22mm / 0.8- 0.9inDrill Bit Diameter: Approx. 18.5mm / 0.7inWire Thread Insert Model Description: For Example: M3 x 0.5 x 1.5D, which means that after the screw is set, the female thread is M3, the pitch is 0.5, the length is 1.5D (Length refers to the length of 1.5 times the diameter, that is, 1.5 x 3= 4.5mm), the length here refers to Is the length after installation.Wire thread inserts are also called threaded sheaths, stainless steel threaded sleeves, wire sleeves, and braces. They are a new type of female thread fasteners made of high-strength, high-accuracy diamond-shaped cross-section steel wire; in aluminum alloy, zinc The application of low-strength engineering materials such as alloys, copper, plastics can significantly improve thread strength and wear resistance.
