براغي رأس سداسي M8-1.25 × 100 مم | فولاذ فئة 8.8 أصفر زنك | خيط كامل (100 / عبوة)

Installed these in a jig for a production run and they threaded in smoothly without any binding. The yellow zinc coating looks consistent and the hex heads give a solid grip with a socket wrench.

I used these to secure a heavy steel bracket to a concrete floor, and the hex head made it easy to tighten with a socket wrench. The yellow zinc coating seems durable, though I didn't test it outdoors.

The 100mm length is perfect for bolting through thick brackets I’m using on a machine frame. Threads cut clean and the hex heads seated snugly with a socket wrench without any stripping.
