براغي ذات رأس أسطواني M2-0.4 × 12 مم | رأس مسطح مع محرك سداسي مجوف | ملولبة بالكامل | فولاد سبائكي فئة 12.9 مع أكسيد أسود حراري (400 / عبوة)

I was worried about stripping them with my hex driver, but the socket drive engaged perfectly on every single screw. These M2 bolts have just the right thread length for the jig I’m building, and the black oxide finish adds a nice tough look. Definitely a solid buy for precision work.

Got these for a small jig I was building, and the black oxide finish is nicely consistent across all 400 pieces. The hex socket drive grabbed firmly without any stripping when I torqued them down. Exactly what I needed for precision work.

These M2 screws are exactly the right size for my jig fixtures, and the 12.9 alloy steel with black oxide feels seriously durable. The hex socket drive grips perfectly with a 1.5mm driver, and 400 pieces in one box means I won’t run out mid-project.
