M8-1 x 80mm 六角ボルト | クラス10.9 鋼 無処理 | 部分ねじ (500 / パック)

The hex head on these M8 screws grabs the socket perfectly without slipping, which made tightening them in tight machine spaces much easier than I expected. The partial threading on the 80mm length is ideal for the specific bracket depth I needed.

These have been great for assembling some custom jigs in my shop—the hex heads seat perfectly with a socket wrench. The partial threading gives just enough grip for heavy loads without needing to run the bolt all the way down. A solid bargain for a box of 500.

Finally, a batch of M8-1 hex head screws where every single one threads cleanly into a tapped hole without binding. The 80mm length is perfect for my equipment mounts, and having 500 in the box means I can stop worrying about running out mid-project.
