براغي رأس سداسي M5-0.8 × 16 مم | فولاذ فئة 10.9 مطلي بزنك أصفر | خيط كامل (500 / عبوة)

These hold up well under torque with a socket; the yellow zinc finish on the 10.9 steel looks uniform across all 500 pieces. Exactly what I needed for a batch of machinery assembly.

The hex head on these M5 screws fits my socket perfectly, making assembly much quicker than with Phillips heads. The yellow zinc finish looks clean and seems durable so far.

I was pleasantly surprised by the quality of these hex screws, especially the consistent yellow zinc finish across all 500 pieces. The class 10.9 steel feels noticeably tougher than standard hardware store bolts, which gives me confidence for a heavy-duty machinery repair.
