براغي رأس أسطوانية M12-1.75 × 30 مم | محرك سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 8.8 مطلي بالزنك (100 / عبوة)

Got these for a jig I’m building, and the 30mm length fits perfectly for clamping down metal plates. The zinc plating looks clean and uniform, and the hex socket bit grabs tight without any wobble.

I needed some solid screws for a heavy-duty machining fixture, and these M12-1.75 x 30mm cap screws held up perfectly with no stripping. The zinc plating seems tough and the hex socket drive made tightening them in tight spots really convenient.

The threads cut clean and true on every single screw, and the zinc plating looks consistent across all 100 pieces. I used a full bag on a jig build and didn't have to chase a single one with a tap.
