💡 What stops stripped plastic mounts from losing grip under stress?
This heating method creates a permanent mechanical key inside soft polymers.
- Melt the target area carefully before seating the knurled brass body
- Align the nut straight down so the ridges bite deeply into fresh molten resin
- Allow the fused metal to harden completely before tightening external hardware
