براغي رأس أسطواني M20-2.5 × 80 مم | محرك سداسي داخلي | ملولبة جزئياً | فولاذ سبائكي فئة 8.8 مؤكسد أسود حراري (25 / عبوة)

Used these to mount a heavy-duty jig on my mill table, and the class 8.8 alloy steel handles the torque without any sign of stripping. The hex socket drive is a breeze to tighten with a standard Allen key, and the 80mm length was perfect for the thick plate.

The black oxide finish on these M20 screws looks great and seems durable, and the hex socket drive made installation a breeze. Perfect for securing heavy machine guards.

Used these M20 cap screws for a precision tooling fixture, and the hex socket drive made tightening them in tight spots much easier than allen bolts. The partial threading gave just enough grip without needing a full thread everywhere. Solid feel for the price.
