براغي رأس مقبس M2-0.4 × 4 مم | رأس زر بمحرك مقبس سداسي | خيط كامل | فولاذ سبائكي فئة 12.9 بأكسيد حراري أسود (400 / عبوة)

The black oxide finish on these M2 screws feels durable and gives them a clean look against the metal parts I'm working with. The hex socket drive made it easy to tighten them into tight spots on my jig without stripping. I'm glad I bought the 400-pack for future small assemblies.

I needed some small metric fasteners for a jig I'm building, and these M2-0.4 x 4mm screws fit the bill perfectly. The hex socket drive makes them easy to tighten without stripping, and the thermal black oxide finish gives them a clean, professional look.

The black oxide finish on these screws has held up perfectly during assembly of a small jig, and the 12.9 alloy steel feels incredibly strong for their tiny size. I've used a couple hundred so far without a single stripped head or broken screw.
