براغي رأس كب M8-1 × 20 مم | محرك سداسي | ملولبة بالكامل | فولاذ سبيكة كلاس 12.9 أكسيد أسود حراري (200/عبوة)

These M8 socket caps are holding up perfectly on a custom CNC fixture I built, and the black oxide finish still looks clean after weeks of coolant exposure. The hex socket drive makes them easy to install in tight spots with a standard Allen key.

The black oxide finish on these looks even better in person, and every single screw threaded cleanly into my jig without any binding. I ordered the 200-pack for a batch of tooling builds, and the consistent quality across the whole box is exactly what I needed.

I've been using these M8 screws for mounting fixtures in my workshop, and the hex socket drive makes them easy to tighten even in tight spaces. The 12.9 alloy steel feels incredibly sturdy, and the 200-count pack is perfect for keeping spares on hand.
