1、Wire thread inserts are also called threaded sheaths, stainless steel threaded sleeves, wire sleeves. A new type of female threaded fasteners 2、The thread inserts are made of high‑strength, high‑accuracy diamond‑shaped cross‑section steel wire 3、Application on low‑strength engineering materials such as aluminum alloy, zinc alloy, alloy, copper, plastic, engineering plastics, etc. will significantly improve thread strength and wear resistance 4、When there is a thread processing error or a damaged internal threaded hole is repaired, the wire thread insert is used as a repairing method, economically and effectively repair the threaded hole 5、Use wire thread inserts to convert between metric and inch threaded holes, convenient and fast 100 x Thread Inserts Item Type: Thread InsertsMaterial: SUS304Model: M5x 0.8x3DThread Specification: M5x 0.8 (mm)Length After Installation: Approx. 15mm / 0.6inNumber of Turns Before Installation: 15.3Outside Diameter Before Installation: Approx. 6.3 ~ 6.6mm / 0.2 ~ 0.3inDiameter of Drilling Drill Bit for Installation: Approx. 5.2mm / 0.2inThread Protective Sleeve Model Specification Description: For Example: M3x 0.5X 1.5D, which means that after the screw set is completed, the internal thread is M3, the pitch is 0.5, and the length is 1.5D (length refers to 1.5 times the diameter, that is, 1.5x3= 4.5mm ), the length here refers to the length after installation.
