براغي رأس مقبس M10-1.5 × 45 مم | محرك سداسي منخفض الرأس | ملولبة جزئيًا | فئة 10.9 فولاذ سبائكي أسود حراري (100 / عبوة)

The low head design on these screws allowed me to recess them flush in a jig where standard cap heads would have stuck out. The black oxide finish looks clean and professional too, and they threaded smoothly into tapped holes.

I was initially worried about the 45mm length being too short for my jig, but the threading is precise and they torqued down perfectly. The black oxide finish feels durable and looks clean against the metal. These should last a while in my workshop setup.

The partially threaded design gave me just the right grip for jig assembly without bottoming out early. These 10.9 alloy screws feel solid and the black oxide finish looks clean on the machine frame.
