China Helicoil Thread Repair Kit - Supplier Factory for Easy Wire Thread Insert Installation

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.

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.
