M18-2.5 x 90mm 六角頭螺絲 | 10.9 級鋼鍍鋅 | 部分螺紋 (25 個/包)

Used these to bolt down a heavy bench grinder in my shop, and the 10.9 grade steel gave me real peace of mind. The partial threading on the 90mm length let me get a solid bite without bottoming out prematurely.

I needed some heavy-duty bolts for a piece of farm equipment and these class 10.9 screws handled the torque without stripping. The partial threading made alignment easier than I expected on a tight assembly.

These M18 hex bolts were exactly what I needed for mounting a heavy motor bracket, and the class 10.9 steel feels seriously tough. The partial threading made it easy to get a solid bite without bottoming out in the blind hole.
