براغي رأس أسطواني M12-1.75 X 80mm | محرك سداسي داخلي برأس كروي | خيط كامل | فولاذ مقاوم للصدأ 316 (50/عبوة)

I needed a full-thread fastener for a marine-grade assembly, and these 316 stainless bolts fit the bill perfectly. The hex socket drive bit snugged up tight without any stripping, and the 80mm length was just right for my jig.

Installed these in a heavy-duty jig at work and the 316 stainless held up perfectly against some harsh coolant spray. The hex socket drive seated cleanly with no stripping, and the button head profile gave just the right low clearance.

Installing these on a custom jig was effortless thanks to the precise threading and that hex socket drive grabs perfectly. The 316 stainless steel feels solid and corrosion-resistant, exactly what I needed for long-term use in a damp workshop.
