50Pcs Thread Inserts Male Female Reducing Nut Repair Tool Stainless Steel Fastener M10x1.25
Feature:
1. When you fit the wire screw set in the screw hole of the workpiece of aluminum alloy and other materials can form a high strength, wearresistant, high accuracy standard female thread.
2. You can repaire the threaded hole in a costeffective 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 works for converting between metric and inch thread holes, very convenient and fast.
4. High strength, high accuracy diamond shaped crosssection steel wire is used. Wire thread inserts are also called threaded sheaths, stainless steel threaded sleeves, wire sleeves, which is a new type of female threaded fasteners.
5. Significantly improve thread strength and wear resistance when applied to lowstrength engineering materials such as aluminum alloy, zinc alloy, alloy, copper, plastic, engineering plastics, etc.

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.
