1、Wire threaded sleeves are also called threaded sheaths, stainless steel threaded sleeves, and wire sleeves, they are a new type of internal threaded fasteners. 2、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, copper, etc., can significantly improve thread strength and wear resistance. 4、As a repair method, threaded holes can be repaired economically and effectively. 5、Convenient and quick to use wire thread inserts to convert between metric and inch threaded holes. 100 x Thread Repair Inserts Item Type: Thread Repair InsertsMaterial: SUS304Model: M5 x 0.8 x 2.5DThread Specification: M5 x 0.8mmLength After Installation: Approx. 12.5mm / 0.5inNumber of Laps Before Installation: 12.6Outside Diameter Before Installation: Approx. 6.3 ~ 6.6mm / 0.2 ~ 0.3inDrilling Drill Bit Diameter 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.
