Sheet Metal Fasteners and Self-Clinching Hardware: Types, Installation, and Best Practices

Sheet metal fasteners, such as self-clinching nuts, studs, and standoffs, provide strong, reusable threads in thin sheet assemblies where traditional methods like welding or tapping are not feasible. These fasteners are pressed into pre-punched holes, displacing the surrounding material to form a permanent, load-bearing anchor. They are widely used in electronics enclosures, aerospace panels, and […]
