M16-2 x 260mm 六角ボルト | クラス8.8 鋼 無処理 | 部分ねじ (10 / パック)

I needed a sturdy hex head for a heavy assembly job, and these 260mm partially threaded screws worked perfectly. The class 8.8 steel feels solid under the wrench, and the 10-pack gave me just enough for the project.

The partial thread on these M16s made lining up the machinery frame way easier than fighting a fully threaded bolt. All ten came clean with no burrs on the hex, and the class 8.8 rating gives me confidence it'll hold under vibration.

Used these to bolt a heavy motor mount to a steel frame, and the 260mm length gave just enough room for a lock washer and nut. The hex heads seated perfectly in my socket without slipping, and the class 8.8 rating handled the torque without stripping.
