براغي رأس سداسي M12-1.75 × 30 مم | محرك سداسي | ملولبة بالكامل | فولاذ سبائكي درجة 8.8 أكسيد أسود حراري (100/عبوة)

Used a couple of these to secure a jig on my milling table, and the hex socket made tightening them a breeze without stripping. The 30mm length was just right for my fixture, and the black oxide seems to handle light shop oil well.

The black oxide finish on these M12 screws held up perfectly during assembly, no chips or flaking. They seated cleanly in the hex driver and the 30mm length was just right for my tooling fixture.

Used these to build a custom jig for repetitive drilling, and the hex socket drive made tightening them into tight spots much easier. The 8.8 alloy steel feels solid and should hold up well under repeated use. Exactly what I needed for precise assembly work.
