M10-1 X 100mm 六角ボルト | クラス8.8 鋼 亜鉛メッキ | 部分ねじ (50個/袋)

I was worried about getting the thread depth right on a machine base, but the 100mm length and partial thread worked perfectly for my needs. The hex head gave a solid grip with a socket wrench, and the zinc coating seems durable.

These have a nice heft to them, the zinc coating looks even and clean. The partial thread on the 100mm length is exactly what I needed for a jig build, and the hex head sat flush in my socket without any wobble. They torqued down smoothly to spec without a hint of stripping.

I needed partially threaded M10s for a specific rigging project and these fit perfectly; the heads are clean and the 100mm length gives just enough bite. They drive in smoothly with a socket and don't strip like some cheaper hardware I've used.
