1、The wire thread insert is made of high‑quality 304 stainless steel, which is resistant to high temperature and corrosion. 2、In the event of thread processing errors or repairing damaged female threaded holes, thread sleeves are a good repair tool. 3、Wire thread insert can be used to convert between metric and imperial threaded holes, which is convenient and fast. 4、The wire screw set is fitted in the screw hole of the metal material workpiece to form a high‑strength, high‑accuracy standard female thread. 5、Wire thread insert is mainly used in aviation, automobiles, lamps, molds, mechanical equipment and other manufacturing fields. 10 x Wire Thread Insert Item Type: Wire Thread InsertMaterial: SUS304Model: M18 x 1.5 x 1DThread Specification: M18 x 1.5Length After Installation: Approx. 18mm / 0.7inNumber of Turns Before Installation: Approx. 9.8 circlesOutside Diameter Before Installation: Approx. 21.4-22mm / 0.8- 0.9inDrill Bit Diameter: Approx. 18.4mm / 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 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.
