DSOS-440-275 | مثبت ذاتي الغلق من بيم #4-40 | فولاذ (50 / عبوة)

Installed these #4-40 fasteners into a sheet metal panel and they seated perfectly flush without any distortion. The steel feels solid and durable, exactly what I needed for a tight assembly.

The threads on these #4-40 steel fasteners cut cleanly into the sheet metal without any slipping, and the self-clinching action held tight after the first press. Perfect for mounting small brackets in a control panel where you can't access the backside.

I needed a reliable way to mount brackets to thin sheet metal, and these self-clinching fasteners installed perfectly with just a standard press. The steel construction feels solid, and the #4-40 threads have held up well during assembly.
