براغي ذات رأس أسطواني من HOLO-KROME 76208 M6-1 X 65mm | محرك سداسي | فولاد سبائكي مع أكسيد أسود حراري (100 / عبوة)

The black oxide finish on these M6 screws makes them look great in my jig setup, and the 65mm length was perfect for securing thicker brackets. They threaded in smoothly without any binding, which is exactly what I needed for precision assembly work.

I used these to replace the fasteners on a jig that kept loosening up, and the hex socket drive makes torquing them down much easier. Thread engagement is precise with no binding, and they fit perfectly in the counterbore. Definitely solid hardware for the price.

The black oxide finish gives these a nice, uniform look, and the hex socket drive seated perfectly on my wrenches with no wobble. Threads were clean and consistent across all 100 pieces, which saved me a lot of cleanup time on a recent jig build.
