💡 What mechanical advantages do crimped blind rivet nuts provide over welded studs in thin gauge alloys?
These threaded inserts act handy when you need strong anchor points without distorting delicate panels. Shop crews grab them to save time on custom frames and repair gigs.
- Align the matching die opening to your exact material thickness for a clean crush point
- Apply steady axial pressure until the deformed collar locks flush against the inner wall
- Chase the internal diameter with a tap before bolting down heavy duty hardware
This straightforward method keeps assemblies flat while delivering reliable shear strength.
