M36-4 X 130mm 六角ボルト | 10.9級鋼 無処理 | 部分ねじ（2 / パック）

Installed these on a heavy press frame, and the partial threading made alignment much easier. The 130mm length was exactly what I needed for that thick flange. Solid holding power so far.

Used these to secure a heavy base plate on a shop press, and the partial threading made alignment much easier. The hex head grabbed cleanly with a standard socket, no slipping at all. Solid hold for the machine frame so far.

The head is machined clean, so the 30mm socket goes on without any wobble. The partial thread gives just enough grip for the deep flange I was bolting down.
