براغي رأس أسطواني M12-1.75 X 30mm | رأس مسطح محرك سداسي | خيط كامل | فولاذ مقاوم للصدأ 316 (100/عبوة)

I was worried about corrosion in my marine jig setup, but these 316 stainless screws handled the salt spray test perfectly with no pitting after a month. The fully threaded body also gave me plenty of bite in some thicker aluminum plates.

The hex socket drive engaged perfectly with my Allen key, no stripping or slipping at all. Used them to secure a heavy-duty tooling fixture, and the 316 stainless steel feels robust enough to handle constant vibration.

I needed M12 screws for a jig I’m building, and the hex socket drive on these made installation quick with a standard allen key. The 316 stainless steel feels solid and should hold up well in a workshop environment.
