براغي ذات رأس أسطواني M6-1 × 30 مم | رأس مسطح بمحرك سداسي | خيط كامل | فولاذ سبائك فئة 12.9 مطلي بالزنك (300 / عبوة)

Bought these for a precision assembly I'm building, and the hex socket drive engages perfectly without any wobble. The zinc plating gives them a clean, uniform finish that looks good even in tight spots.

I needed some strong fasteners for a jig I was building, and these hex socket drive bolts threaded in smoothly without any binding. The zinc plating gives them a clean look and the 12.9 alloy steel feels plenty tough for my precision tooling setup.

The hex socket drive on these M6-1 x 30mm screws grabbed my driver perfectly, and the fully threaded design made alignment a breeze for my jig setup. The zinc plating looks clean and even across all 300 pieces.
