Features High-Strength Threading Solution - Achieve a durable, wear-resistant, and precise female thread in aluminum and other materials with ease Cost-Effective Repair Method - Fix damaged or erroneous threaded holes efficiently without extensive repairs, saving you time and money Versatile Thread Conversion - Easily switch between metric and inch thread holes, providing flexibility for various applications Premium Quality Construction - Crafted from high-strength, diamond-shaped cross-section steel wire for enhanced durability and reliability Suitable for Low-Strength Materials - Perfect for aluminum, zinc, copper, and plastics, significantly boosting thread strength and wear resistance Features: 1、When you fit the wire screw set in the screw hole of the workpiece of aluminum alloy and other materials, the product can form a high？strength, wear？resistant, high？accuracy standard female thread 2、You can repaire the threaded hole in a cost？effective manner. When a thread error occurs or a damaged female threaded hole is repaired, threaded insert can be used as a repair method 3、Thread inserts can be used to convert between metric and inch thread holes, very convenient and fast 4、Using high？strength, high？accuracy diamond？shaped cross？section steel wire. Wire thread inserts are also called threaded sheaths, stainless steel threaded sleeves, wire sleeves, which is a new type of female threaded fasteners 5、Applied to low？strength engineering materials such as aluminum alloy, zinc alloy, alloy, copper, plastic, engineering plastics, etc. can significantly improve thread strength and wear resistance Specification: Item Type: Thread Inserts Material: SUS304 Model: M4x0.7 Thread Specification: M4x0.7 (mm) Outside Diameter Before Installation: Approx. 5 ~ 5.m / 0.2 ~ 0.2in Diameter of Drilling Drill Bit for Installation: Approx. 4.2mm / 0.2in 1D/1.5D/2D/2.5D/3D: Length After Installation: Approx. 4mm / 0.2in 6mm / 0.2in 8mm / 0.3in 10mm / 0.4in 12mm / 0.5in Number of Turns Before Installation: 4/6.6/9.1/11.7/14.2 Thread Protective Sleeve Model 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. How to Use: 1. Drilling Use the drill bit of the size listed in the parameter table of the wire thread insert to drill the hole. Be careful not to drill the hole into a cone shape.
