Feature: 1. Used in the screw hole of the workpiece such as aluminum alloy to form a high‑strength, wear‑resistant, high‑accuracy female thread. 2. Repair threaded holes economically and effectively, with low cost and high efficiency, which is to use. 3. Simple to operate, it can convert metric and inch threaded holes conveniently and quickly. 4. Suitable for low‑strength engineering materials such as aluminum alloy, zinc alloy, copper, plastic, etc. 5. Made of high quality SUS304, with good corrosion resistance, heat resistance, low temperature strength and mechanical properties. Specification: Item Type: Thread Repair Insert Material: SUS304 Model: M5 x 0.8 x 1.5D Thread Specification: M5 x 0.8mm Length After Installation: Approx. 7.5mm/0.3in Turns Before Installation: 7.1 Outside Diameter Before Installation: Approx. 6.3-6.6mm/0.2-0.3in Diameter of Mounting Drilling Drill Bit: Approx. 5.2mm/0.2in Application: It is a new type of internally threaded fastener, which is made of high-strength, high-precision -shaped crossed-section steel wire; it is suitable for low-strength engineering materials such as aluminum alloy, zinc alloy, copper, plastic, and phenolic plastic, etc. which can significantly improve thread strength and wear resistance. Model Specification Description: For example: M3x0.5x1.5D means that after the screw is mounted, 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 is the length after installation. Package List: 100 x Thread Repair Inserts
