Set specifications are typically defined by the metric or imperial (UNF/UNC) internal thread size formed by the insert:
1) Common metric set sizes: M3, M4, M5, M6, M8, M10, etc.
2) Common imperial set sizes: #10-32, 1/4-20, 5/16-18, 3/8-16, etc.
3) Insert Length: Sets typically offer various lengths of 1D, 1.5D, and 2D (D represents the thread diameter) to accommodate varying material thicknesses and strength requirements.

Wire thread insert
Material: Most are made of high-quality 304 or 316 stainless steel, offering exceptional strength, elasticity, and excellent corrosion resistance. A few kits may be made of carbon steel (with surface treatment) or copper alloy. Types: Typically available in free-running and screw-lock types. The screw-lock type has a tapered section in the middle of the insert, preventing loosening due to vibration.
Specifications: Sets typically focus on one or a few common sizes (e.g., M4-M8) and include inserts of various sizes.
Specialized Installation Tools
Tap: Used to create the specific threaded holes required for installing wire thread inserts. The tap is clearly marked with the corresponding wire thread insert size.
Insertion Tool: Typically a handle with a guide rod. The insert is placed on the guide rod and then rotated clockwise to insert it into the tapped hole. Removal Tool: Used to remove damaged or improperly installed inserts. The guide rod is designed with reverse threads, allowing it to hook onto the insert's mounting handle and be removed by rotating counterclockwise.
1) One-stop solution: All necessary tools are provided, from drilling and tapping to installation and removal, eliminating the need for users to manually match tools, saving time and effort.
2) Guaranteed Installation Quality: Specialized tools ensure quick, correct, and vertical installation of threaded inserts, eliminating installation failures or insert damage caused by tool mismatch.
3) High Strength and Wear Resistance: Threads formed in soft materials (such as aluminum, magnesium alloys, and plastics) are significantly stronger than the original material, significantly improving wear resistance and allowing the screw to be repeatedly installed and disassembled without damage to the screw hole.
4) Excellent Anti-vibration and Anti-loosening: The spring effect of the threaded insert effectively absorbs shock and vibration, preventing loosening. Screw-locking types offer even better results.
5) Thread Repair: Threaded inserts are the most effective and economical method for repairing damaged or stripped threads, restoring them to their original dimensions or even greater strength.
