براغي رأس مقبس M6-1 X 180mm | محرك مقبس سداسي | سنون جزئية | فولاذ سبائكي فئة 12.9 أكسيد أسود حراري (50/عبوة)

The 180mm length was perfect for a deep jig assembly I was working on, and the black oxide finish on these screws resists oil and dust far better than standard zinc. They torqued down smoothly with no stripping, even at high spec. Exactly what I needed for heavy-duty machinery repair.

The hex socket drive made installation so easy with just an Allen key, and the black oxide finish adds a nice, durable look. These 180mm screws fit perfectly into my jig setup. Definitely sturdy enough for precision work.

I needed a batch of 180mm screws for a custom jig and these M6-1s held alignment perfectly during assembly. The partially threaded shaft kept the clamp loads where I needed them, and the black oxide finish has held up nicely.
