Thread inserts introduction
The wire thread insert is made of high-hardness, corrosion-resistant steel wire with a diamond-shaped cross-section. It is a spring-like concentric body of internal and external threads. The cross-sectional shape of the standard internal thread used for fastening parts is a combination of two internal and external threads. Wire thread inserts are divided into two types: ordinary type and locking type, each with or without breaking grooves and with breaking grooves.
Product advantages
1. enhance the connection strength, improve the connection conditions. Wire thread insert is selected from the aluminum, magnesium and other low-strength material, can be avoided slide wire, wrong tooth phenomenon and obtain a good connection performance.
2. Wear resistance. Used in frequently disassembled parts, it can greatly improve the service life of the thread.
3. Increase the bearing surface. For the strength of the connection required force does not increase the diameter of the screw portion.
4. Anti-loosening. In particular for aerospace and other products requiring high safety factor of the occasion.
5. Easy to maintain. Install the damaged screw hole into the steel wire screw sleeve and continue to use it after repair to avoid the possibility of damage to the workpiece.
