براغي رأس مقبس M6-1 × 195 مم | محرك سداسي | ملولبة جزئيًا | فئة 12.9 من سبائك الصلب بأكسيد أسود حراري (50 / عبوة)

Installing these in a tight jig setup was a breeze thanks to the hex socket drive and the partially threaded design. The black oxide finish looks durable and professional.

The 195mm length was exactly what I needed for a deep jig assembly, and the hex socket drive made tightening effortless. They feel solid and precise for tooling work, though having 50 in the pack is more than I'll use anytime soon.

The black oxide finish on these screws looks great and handled the assembly of my machining jig without a hitch. The hex socket drive engaged the driver bit perfectly, no stripping. The 195mm length was just right for the thick metal plates I was working with.
