FHS-440-14 | مسامير PEM ذاتية التثبيت #4-40 | فولاذ مقاوم للصدأ 18-8 (50 / عبوة)

Had to restock these for our sheet metal fixtures and the 18-8 stainless finish is holding up perfectly against the shop's humidity. The #4-40 threads cut clean every time, no galling or stuck studs even after repeated installs.

Pressed a full batch into 0.06" aluminum panels and every single one seated square without any thread deformation—the stainless holds up to repeated wrenching. Fifty in the pack is plenty for a couple of small projects, and the #4-40 threads mate cleanly with standard hardware.

These #4-40 studs pressed perfectly into the 0.060" sheet steel on my control panel project. The stainless steel threads are clean and the self-clinching action held tight without any distortion.
