💡 How to mount heavy hardware on thin sheet metal without weakening the base material?
Fabricators stash these handy inserts in their shops because they skip the hassle of chasing threads or fighting stripped holes. You pop the unit flat against the blank frame, run a quick resistance pass, and walk away with a load ready thread on both sides. Here is why they cut down on build time:
- double tab geometry bites into cold rolled steel while heat fuses the collar for unshakable retention
- tough low carbon makeup accepts standard mig passes without special gas setup
- centered hole alignment keeps fasteners square and stops cross threading during assembly
