Reusable Brass Thread Insert Nuts For Injection Molding Plastic Threaded Inserts
Information
Steel threaded inserts can be used to strengthen and prolong the service life of the thread. Each insert member load balancing by bolts and holes, thereby maintaining or increasing the pull-out resistance. After installing the wire thread insert, a more uniform load and stress distribution can be obtained. Free wire threaded insert 304 is typically made of rolled (18-8) made of rhombic cross section stainless steel wire.
The collar is made of copper, phosphor bronze, its conductivity is significantly improved, and non-magnetic. Suitable for products with special requirements for conductivity and magnetism.
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.
