براغي رأس مقبس M6-1 X 35mm | رأس منخفض سداسي | جزئي الخيوط | فولاذ سبائك فئة 10.9 مؤكسد أسود حراري (200 / عبوة)

The partially threaded design made aligning my jig plates much easier, and the black oxide finish looks professional. They tightened down smoothly without any stripping issues.

I've been using these for mounting fixtures on my CNC router table and the low head profile makes a huge difference in tight spots. The black oxide finish looks great and seems to resist rust better than the zinc ones I used before.

My new jig build needed these exact screws, and the low profile hex head sits perfectly flush so nothing snags during operation. The black oxide finish also kept them from rusting when I accidentally left a few out overnight in the shop.
