FHS-440-8 | مسامير تثبيت ذاتية PEM #4-40 | فولاذ مقاوم للصدأ 18-8 (200/عبوة)

These self-clinching studs press in smoothly and hold tight in thin sheet metal, so I don't have to juggle nuts on the backside anymore. The #4-40 threads are clean and consistent across the whole batch, saving me time during assembly.

Used a handful of these for a thin metal bracket that kept stripping threads with regular screws, and they held tight after installation. The stainless steel feels durable and the #4-40 threading was clean with no burs. Exactly what I needed for attaching components to sheet metal.

Put these in for a small panel repair job and the self-clinching feature saved me from having to access the backside. The 18-8 stainless steel feels sturdy and the threads cut cleanly into the sheet metal. Exactly what I needed for #4-40 work.
