براغي رأس أسطوانية M3-0.5 × 12 مم | محرك سداسي | ملولبة بالكامل | درجة 8.8 سبيكة فولاذ مطلية بالزنك (800 / عبوة)

Installing these on a precision assembly and the hex socket drive grabs perfectly, no stripped heads. The 12mm length is just right for my application, and the zinc plating looks clean.

I needed some sturdy fasteners for a jig I was building, and these M3 socket cap screws held up perfectly under repeated torque without stripping. The hex socket drive made installation smooth with just a standard allen key.

These screws are the perfect fit for my 3D printer’s linear rail carriages, and the zinc plating on the heads is holding up well after a few adjustments. The hex socket drive grabs nicely with my Allen key, making installation a breeze. I’m glad I stocked up with the 800-count pack.
