Wire Thread Inserts are also known as Threaded Ferrules, Stainless Steel Threaded Ferrules, Wire Ferrules, which is a new type of female threaded fasteners 2. The product is made of high-strength, high-precision -shaped cross-section steel wire and is very Application to low strength engineering materials such as aluminum alloy, zinc alloy, alloy, copper, plastic, engineering plastic, etc., greatly improves thread strength and wear resistance 4. When a thread processing error occurs or a damaged internally threaded hole is to be repaired, the wire thread insert can be used economically and effectively as a repair method 5. You can use wire thread inserts to conveniently and quickly convert between metric and imperial threads Specification: Item Type: Threaded Inserts Material: SUS304 Model: US Standard 5/ 16 inch-18 x 1.5 D Diameter: Approx. 7.938 mm / 0.3 inch Pitch: 1.41 (mm) Number of turns before installation: 6.8 Length After Installation: Approx. 11.9mm Outer Diameter Before Installation: Approx. 9.6~10.2mm/0.4~0.4inch Diameter of Drill for Installation: Approx. 8, 3mm / 0.3inch Thread Sleeve Model Specification Description: For example: M3 x 0.5 x 1.5D, which means that after completing the screw kit, the internal thread is M3, the pitch is 0.5 and the length is 1.5D (Length refers to 1.5 times the diameter, ie 1.5 x 3 = 4.5mm), the length here refers to the length after installation, and peel off the protective layer on the part which the wire must be connected. Step 2: Loosen the terminal block screw and prepare the stripped wire Step 3: Insert one end of the stripped wire into the terminal and then pull a wire tighten the screw
