M18-2.5×75mm 六角穴付きボルト | クラス10.9 スチール プレーン | 部分ねじ (100個/パッケージ)

These hex heads fit my socket perfectly with zero play, and the 75mm length with partial threading gave me just the right grip for mounting a heavy jig plate. I’ve used a dozen so far and not one stripped or bent under the torque.

I needed some heavy-duty bolts for a tractor attachment, and these hex head cap screws drove in perfectly with a socket; the 10.9 steel feels solidly machined.

The thread engagement on these is spot-on, and the 10.9 grade gives me real confidence when torquing them down on the press frame. At 75mm with partial threads, they're long enough for thick flanges without bottoming out. A hundred per pack means I've got spares for the next job.
