M8-1.25 X 22mm براغي رأس مقبس | محرك سداسي | ملولبة بالكامل | فئة 8.8 فولاذ سبائكي أسود حراري (200 / عبوة)

The black oxide finish on these is holding up well in my shop, no rust after a week of use. They fit perfectly into my tooling fixtures, and the hex socket drives cleanly without stripping. Really solid screws for the price per pack.

These black oxide screws look clean and professional on my latest jig build. The hex socket drive made them easy to install even in a tight spot. Exactly the quality I needed for tooling work.

Needed some for a jig I was building, and the 22mm length was exactly what the drawing called for. The hex socket drive made install a breeze, though the black oxide finish does get slightly messy if you handle them a lot.
