براغي رأس سداسية M10-1.5 X 70mm | رأس مسطح محرك سداسي | ملولبة جزئياً | سبائك فولاذ فئة 10.9 أكسيد أسود حراري (100 / عبوة)

The black oxide finish on these is exactly what I look for—gives them a solid, uniform look and they thread cleanly into tapped holes without any binding. Partial threading on the 70mm length is perfect for clamping down thicker tooling plates where I need full thread bite at the end.

Used them to bolt down a couple of jigs on the mill, and the 10.9 alloy steel feels rock solid under load. The black oxide finish looks clean and hasn't shown any rust after a week of shop use. Threading starts smooth and the hex drive bites perfectly every time.

The partial threading on these M10-1.5 screws made aligning them in my jig assembly much easier than fully threaded bolts. They seated firmly without wobbling.
