KFSE-440-20 | #4-40 صواميل تثبيت ذاتية PEM | فولاذ (50/عبوة)

Perfect fit for a thin metal plate I was working on — the self-clinching action seated flush in one press. Much cleaner than trying to tap a hole in thin steel.

Used these to attach a small bracket to a thin metal panel and the self-clinching design held tight without needing a separate nut driver. The steel finish feels sturdy enough for the application.

The steel material on these #4-40 nuts feels really solid, and the self-clinching design locked them into my thin metal panel perfectly. I used them for a custom electronics enclosure, and the threads hold bolts securely without stripping. Exactly what I needed for permanent fastening.
