Application of Three-Hole Type Tapping Thread Bushing
The Three-Hole Type Tapping Thread Bushing is a new type of fastener that makes the thread strengthens. The three-hole self-tapping thread insert can form a higher-strength internal thread hole when it embedded in soft materials such as plastic, aluminum alloy, cast iron, copper, etc. It can also repair the damaged internal thread.
Advantages of Three-Hole Type Tapping Thread Bushing
1. No need to pre-tapped on the base material when use the Three-Hole Type Tapping Thread Bushing.
2. Three-Hole Type Tapping Thread Bushing with function of repairing the broken female thread, and a same screw can be used on it after the thread is repaired.
3. Three-Hole Type Tapping Thread Bushing has strong resistance to vibration and can prevent loosening.
4. Three-Hole Type Tapping Thread Bushings are easier and faster to install than ordinary wire threaded inserts.
