Item Type: Wire Thread Insert Material: SUS304 Model: M1.6 x 0.35 Thread Specification: M1.6 x 0.35 Outside Diameter Before Installation: Approx. 2.1-2.3mm or 0.1-0.1in Drilling Drill Bit Diameter: Approx. 1.6mm or 0.1in Length After Installation: Approx. 1D: 1.6mm or 0.1in 1.5D: 2.4mm or 0.1in 2D: 3.2mm or 0.1in 2.5D: 4.0mm or 0.2in 3D: 4.8mm or 0.2in Wire Thread Insert Model Description: For Example: M3 x 0.5 x 1.5D, 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 is 1.5 times the diameter, that is, 1.5 x 3=4.5mm ), the length here refers to the length after installation. Wire thread inserts are also called threaded sheaths, stainless steel threaded sleeves, wire sleeves, and braces. They are a new type of female thread fasteners made of high-strength, high-accuracy diamond-shaped cross-section steel wire in aluminum alloy, zinc The application of low-strength engineering materials such as alloys, copper, plastics can significantly improve thread strength and wear resistance.
