💡 Why choose brass heat set inserts over standard metal screws for plastic projects?
Standard metal screws chew up soft plastic material and strip out whenever torque increases during operation.
- Brass inserts melt directly into the base material to form a permanent bond that stays handy under stress and vibration.
- Heat-set threading fixes stripped holes fast while giving you a clean finish for DIY robots and enclosure assemblies.
- Knurled edges dig into melted plastic to lock parts together securely without loosening over time.
