KFE-143-8 | صواميل ذاتية الثني من PEM | فولاذ (100 / عبوة)

Installed a dozen of these into 1.5mm sheet metal and they pressed in smoothly without any deformation. The steel construction gives them a solid bite when threading in a bolt. Exactly what I needed for a clean, permanent threaded hole.

The steel threads catch perfectly in thin sheet metal, and the package gave me exactly 100 cleanly formed nuts with no burrs. I used them on a control panel enclosure and every one seated flush without spinning.

I needed a batch of reliable self-clinching nuts for a steel bracket assembly, and these grabbed the metal firmly without any extra tools. The hundred-pack means I have plenty left for future projects, which is a nice bonus.
