M12-1.5 X 60mm 六角ボルト | クラス10.9 鋼 亜鉛メッキ | 部分ねじ (50 / パック)

The zinc plating on these M12 screws is holding up well in my shop environment, no rust after a week. The partially threaded design made them perfect for securing a heavy machine base where I needed full thread engagement in the first section.

Perfect threads on every single screw, they seated smoothly into the pre-tapped holes without any binding. The hex head gave my socket a solid grip, and the zinc plating looks clean and durable.

These held up perfectly when I torqued them down on a heavy equipment frame — the zinc plating still looks good after a few weeks in a damp shop. The partial threading made alignment much easier than fully threaded bolts I've used before.
