براغي ذات رأس سداسي M20-2.5 X 75mm | فولاذ من الفئة 10.9 مطلي بالزنك | ملولبة بالكامل (80 / Pkg.)

Used these to secure a milling machine base to the floor, and the zinc plating held up well in the damp workshop. The 10.9 grade gives real peace of mind for heavy loads, and the full threading made alignment easier than expected.

Had to replace some worn bolts on heavy press equipment and these class 10.9 steel screws fit the bill perfectly — the zinc plating makes them easy to grip even with greasy gloves.

The hex head on these M20 bolts grabbed my socket perfectly without any slippage, and the zinc plating seemed even and consistent across all 80 pieces. Used them to secure a heavy workbench frame to concrete anchors, and they threaded in smoothly the whole way.
