Lier-Metal Wire Coil Insert

Steel thread insert is a new type of fastener. It is precision formed coils of stainless steel wire having a diamonds shaped cross-section. Thread insert is used for manufacturing high strength, wear-resistance, high-duty, vibration proof and exchangeable bolted connections in metallic and non-metallic materials such as stainless steel, Al, alloy, iron, plastic. It is benefits all those suffering from misaligned damaged or worn female threads as well. Metric system and BS can be supplied on the customers request.

Lier-Metal Wire coil also can improve threads stress state and to be spring connection, remove the errors of pitch and thread angle, pretectthe thread avoiding to be broken, and extend working time.
It prevents the thread rusting, stucking, trip with perfect corrosion, high heat and abrasion resistant in many kinds environments, it also can repair the interal thread
Our precision type: 6H, 5H, 4H

Advantage:
1. Enhancing the connected strength of internal thread.
2. Improving the working life.
3. Reducing the weight of the casting housing.
4. Easy to repair the internal thread and assemble.
5. Excellent material quality.

Material: Stainless steel, aldary, super alloy.
