براغي رأس مقبس M4-0.7 × 30 مم | محرك مقبس سداسي | ملولبة بالكامل | فولاذ مقاوم للصدأ 18/8 (600/عبوة)

I needed a bunch of M4s for a precision fixture and these stainless ones threaded smoothly straight out of the box, with a consistent hex socket depth that made assembly fast. The 600 count bag is exactly what I needed for this project.

Used a full bag of these on a jig I was building and every single one threaded cleanly into tapped holes with no binding. The 18/8 stainless finish looks great and seems corrosion-resistant enough for my garage workshop. Finally got the lengths I need without overpaying at the hardware store.

The hex socket drive bit snugly without any wobble—exactly what I need for precise jig assembly. These 18/8 stainless screws held up perfectly during my latest tooling project, no stripping issues.
