براغي رأس أسطواني بمقبس سداسي M8-1.25 × 10 مم | مقبس سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 بأكسيد أسود حراري (200 / عبوة)

The black oxide finish on these screws really holds up well against scuffs in my tooling setup, and the 12.9 grade gives me confidence they won't shear under load. Exactly what I needed for a precision assembly.

I’ve used these for a few jig builds and the Class 12.9 alloy holds up noticeably better than the cheaper 8.8s I had before. The hex socket drive fits snugly with no stripping, and the 10mm length is spot-on for thin plates.

The black oxide finish on these screws seems really durable, and they threaded smoothly into my jig without any binding or galling. I've already used a dozen of them for different assemblies and they hold firm.
