براغي رأس سداسي M5-0.8 × 20 مم | فئة 10.9 من الصلب مطلية بالزنك الأصفر | خيط كامل (500 / عبوة)

Got these for a batch of machine guards and the 10.9 grade steel really holds torque without stripping. The yellow zinc finish is holding up well against shop oils and occasional moisture.

The hex head grips my socket wrench perfectly without any stripping, and the Class 10.9 steel feels seriously tough. Threads ran smooth into my steel frame, and having 500 in the box means I’m set for any project that pops up.

I needed a full 20mm length for a tight bracket assembly, and these hex heads fit perfectly with a socket wrench. The yellow zinc coating looks solid and they threaded smoothly into pre-tapped holes without binding.
