KFH-440-8 | صواميل PEM ذاتية التثبيت مقاس #4-40 | فولاذ (100 قطعة/عبوة)

These self-clinching nuts installed cleanly on the first try without needing access to the back side. The steel build feels solid and the #4-40 threading matched perfectly with my studs. Exactly what I needed for a secure fastening job.

I was worried about alignment, but these #4-40 steel nuts pressed in cleanly and held tight during assembly. The 100-count package should last me through several projects.

The self-clinching action worked perfectly on a thin metal panel I was repairing, and the #4-40 threads engaged smoothly with the bolt. For a hundred-pack of steel nuts, this is a solid value that saved me a trip to the hardware store.
