Features HIGH STRENGTH: the threaded adapter can form a high‑strength, wear‑resistant, high‑accuracy standard female thread if you fit the wire screw set in the screw hole of the workpiece of aluminum alloy and other materials THREAD REPAIR : You can repaire the threaded hole in a cost‑effective manner. This reducing nut is a good tool When a thread error occurs or a damaged female threaded hole is repaired, threaded insert is a repair method QUICKLY CONVERSION: These steel wire inserts can be used to convert between metric and inch thread holes, which is convenient and fast THREAD SLEEVE FUNCTION:A new type of female threaded fasteners. Adopt high‑strength, high‑accuracy diamond‑shaped cross‑section steel wire. Also called threaded sheaths, stainless steel threaded sleeves, wire sleeves APPLICATION:The Thread Extension Tool Works for improving thread strength and wear resistance significantly when used on low‑strength engineering materials such as aluminum alloy, zinc alloy, alloy, copper, plastic, engineering plastics, etc. Specification: Item Type: Thread Inserts Material: SUS304 Model: M6x1 Thread Specification: M6x1 (mm) Outside Diameter Before Installation: Approx. 7.5 ~ 7.9mm / 0.3 ~ 0.3in Diameter of Drilling Drill Bit for Installation: Approx. 6.3mm / 0.2in 1.5D/2D/3D: Length After Installation: Approx. 9mm / 0.4in 12mm / 0.5in 18mm / 0.7in Number of Turns Before Installation: 6.9/9.6/14.9 Specification Description: For Example: M3x0.5X1.5D, which means that after the screw set is completed, the female 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.
