براغي رأس مقبس M2-0.4 × 6 مم | رأس مسطح محرك سداسي | ملولبة بالكامل | فئة 10.9 فولاذ سبائكي أسود حراري (400 / عبوة)

The hex socket drive on these M2 screws made installation into tight jig holes effortless, and the black oxide finish looks clean and professional. They threaded smoothly without any binding, and the full thread grip feels solid for precision assemblies.

I needed some small, high-strength screws for a jig I was building, and these M2s fit the bill perfectly. The hex socket drive made them much easier to install than I expected for such a tiny fastener, and the black oxide finish seems durable.

The black oxide finish on these screws hasn't stripped or chipped even after repeated wrenching in and out of my jig fixtures. For 400 pieces at this price, the Class 10.9 strength is a solid deal.
