M10-1 x 20mm 육각 머리 볼트 | 클래스 8.8 강재 무도금 | 풀 나사 (200개/팩)

Needed a handful for a jig I was building, and these M10-1s threaded in cleanly without any gunk or burs in the threads. The Class 8.8 steel feels sturdy enough for light machinery work.

The hex head sat flush in my socket wrench with zero wobble, and the class 8.8 steel handled the torque on my workshop press without stripping. Fully threaded meant I could cinch down a bracket exactly where I needed it, no extra washers to fuss with. These are my new go-to for metal frames.

Fits perfectly on my machine’s adjustment brackets, and the fully threaded shaft grabs cleanly from the first turn. Was surprised the hex head took a socket without slipping—solid bite for a 20mm bolt. These are going to hold up fine for the price.
