M12-1.75 X 180mm 六角ボルト | クラス10.9 鋼 無処理 | 部分ねじ (15本/パック)

These M12 bolts fit perfectly into the threaded holes on my press jig, and the 180mm length was just right for the job. The partially threaded shank made aligning the plates much easier than with fully threaded bolts I've used before.

I've been using these hex head cap screws to secure a steel base plate in a workshop jig, and the partially threaded shank made alignment much easier than fully threaded bolts. The 10.9 grade steel feels really solid under torque, and they came out of the package with clean, uniform threads.

Used these for mounting a heavy motor on a steel frame — the 10.9 grade held up perfectly under torque without any flex. The hex heads seated cleanly with a standard 19mm socket.
