Customer Reviews (4.8 / 5 · 5 reviews)

Alexander ★★★★★

I needed #4-40 hardware for a thin aluminum bracket and these self-clinching nuts pressed in cleanly without any deformation. They feel solid and should hold up well under repeated assembly.

Madison ★★★★★

These steel nuts press into thin sheet metal cleanly and hold tight—tested a few with a #4-40 screw and they didn’t spin at all. Perfect for mounting small PCBs where you can’t tap threads.

Lucy ★★★★★

Installed a dozen of these #4-40 nuts into a thin steel bracket today and they pressed in cleanly without any distortion. The steel feels sturdy and the threads caught perfectly on the first screw.
