براغي رأس كبسولة M6-1 × 75 مم | محرك مقبس سداسي | ملولبة جزئيًا | فئة 8.8 فولاذ سبائكي مؤكسد أسود حراريًا (200 / عبوة)

Perfect fit for the tooling fixture I built last week—the partial threading made assembly much easier. The black oxide finish seems durable and hasn’t shown any wear after a few test runs. Exactly what I needed for precision work.

The black oxide finish on these M6-1 screws gives them a nice, uniform look for my jig builds, and the 75mm length with partial threading seated perfectly in my fixture plates. All 200 arrived clean and defect-free, which saved me a trip back to the hardware store mid-project.

I needed a batch of partially threaded socket cap screws for a jig build, and these 75mm long M6-1s fit perfectly. The hex socket drive engages cleanly without stripping, and the black oxide coating looks uniform across all 200 pieces.
