براغي رأس مقبس M3-0.5 × 14 مم | رأس مسطح محرك مقبس سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 10.9 أكسيد أسود حراري (800 / عبوة)

I needed a bulk pack for tooling repairs, and the consistent thread engagement on these M3 screws saved me a lot of rework. The black oxide finish held up well during assembly without any galling.

Perfectly sized for jig work—these screws hold tightly in aluminum plate without stripping. The hex socket drive makes installation quick with a standard ball-end driver. Exactly what I needed for my precision assembly projects.

I was pleasantly surprised by the precise threading on these M3 screws—every single one seated perfectly in my jig without any cross-threading. The black oxide finish looks clean and professional, and having 800 in one package means I won't need to reorder for a long time.
