M22-2.5 X 200mm براغي ذات رأس أسطواني بمقبس سداسي | محرك مقبس سداسي | خيط جزئي | فولاذ سبائكي فئة 12.9 مع أكسيد أسود حراري (10 / عبوة)

Needed these for a custom jig and the partially threaded length gave me perfect grip depth without bottoming out. The black oxide finish looks properly done and they came out of the bag with no surface grinding marks. Price is fair for 12.9 alloy steel at this size, honestly.

The hex socket drive on these M22 screws made tightening them in tight spaces a breeze, and the 12.9 alloy steel feels rock solid. They fit perfectly into my milling machine's tooling fixture without any wobble.

I needed strong bolts for a heavy jig I was building, and these M22 socket cap screws fit perfectly in the hex drive without any slipping. The 200mm length combined with partial threading made alignment a breeze.
