1、This is a new type of female threaded fasteners. Wire thread inserts are also called threaded sheaths, stainless steel threaded sleeves, wire sleeves 2、The product is 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. to improve thread strength and wear resistance significantly 4、When there is a thread processing error or a damaged internal threaded hole is repaired, the wire thread insert can be 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, which is convenient and fast, very practical Item Type: Thread Inserts Material: SUS304 Diameter: Approx. 4.826mm / 0.2in Pitch: 1.06 (mm) Length After Installation: Approx. 4.8mm / 0.2in Number of Turns Before Installation: 3.3 Outside Diameter Before Installation: Approx. 6.1 ~ 6.6mm / 0.2 ~ 0.3in Diameter of Drilling Drill Bit for Installation: Approx. 5.1mm / 0.2in Thread Protective Sleeve Model Specification Description: For Example: M3x0.5X1.5D, 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. 50 x Thread Inserts
