Customer Reviews (4.8 / 5 · 5 reviews)

Carter ★★★★★

Finally a self-clinching nut that actually stays put during assembly; these #4-40s grip the panel tightly without spinning. I used a full hundred-pack on a recent project and didn't lose a single one.

Lily ★★★★★

The steel construction on these #4-40 clinch nuts felt solid and they seated perfectly flush in my 0.060" sheet metal without any deformation. I used them to create clean, permanent threads for mounting a PCB and they held up great when torqued down.

Benjamin E. ★★★★★

I had to fasten a few brackets to thin sheet metal, and these self-clinching nuts worked perfectly—they stayed tight without needing backing support. The steel construction feels durable enough for repeated use, and a single package of a hundred is more than enough for most small projects.
