M6-1 X 50mm 外六角螺絲 | 10.9級鋼黃色鍍鋅 | 部分螺紋 (200 / 包)

I’ve been using these M6 bolts in a heavy-duty frame assembly and the hex head grabs perfectly with a socket. The yellow zinc finish looks clean and feels tough enough for machine-grade work. A solid 200-count box for serious projects.

The partially threaded design made alignment a breeze when I was bolting down a steel jig—no more fighting the threads through the whole hole. The yellow zinc finish held up fine under a bit of shop grime, and the hex head took a socket wrench without slipping once.

The hex head on these M6-1 cap screws grabs the socket perfectly without slipping, and the partial threading makes them ideal for flush-mount applications. They’ve held up well during my equipment assembly project without any visible wear on the yellow zinc coating.
