M20-2.5×100mm 육각 머리 볼트 | 클래스 10.9 강철 황색 아연 도금 | 풀 스레드 (25개/팩)

I needed some heavy-duty fasteners for a press build, and these M20 hex heads threaded in smoothly without binding. The yellow zinc finish looks solid, and the 10.9 grade gives me confidence they’ll hold torque.

The threads are clean and the yellow zinc finish looks evenly applied, so they’ll hold up fine in my shop. I grabbed these for a heavy bracket assembly and the hex heads seated perfectly with a socket.

I needed some heavy-duty bolts for a piece of shop equipment, and these M20s fit the bill perfectly. The 10.9 grade steel feels solid and the yellow zinc coating looks like it’ll hold up fine in a slightly dusty environment. Only took a few minutes with a socket wrench to get them all torqued down.
