Common Problems and Solutions for Self-Tapping Inserts：
1.Insert Breakage:
Cause: Base material too hard/speed too high.
Solution: For steel base materials, use pre-tapped inserts, reduce speed, and apply cooling and lubrication.
2.Thread Loosening:
Cause: Insufficient installation torque or base material wear.
Solution: Apply thread locker (such as Loctite 243) and strictly adhere to the required torque.
3.Base Material Cracks (Plastic/Wood):
Cause: Hole diameter too small or threading too quickly.
Solution: Enlarge the pre-drilled hole by 0.1mm and thread in stages (thread in one turn → back out → repeat).
