M36-4×110mm 六角ボルト | 10.9級 鋼 無処理 | 半ねじ (2本/パック)

Heavy duty and precise, these screws fit perfectly in my press jig where I needed a solid hold. The Class 10.9 steel feels noticeably tougher than standard bolts, and the hex head makes it easy to get a good torque with a socket.

The partially threaded section grabbed cleanly when I torqued them down, and the Class 10.9 hardness held up without any deformation under heavy load. Exactly what I needed for the equipment frame repair—solid and precise.

The 10.9 grade is clearly legit—these hex heads took a full torque without a hint of stripping, and the partial threading made alignment in our fixture a breeze. Two in the pack was enough to finish the job, and they came out of the box clean with no oil residue to wipe off.
