M22-2.5 x 120mm 六角頭螺絲 | 8.8級鋼 無處理 | 部分螺紋（10入/包）

Had to tighten some heavy equipment mounts and these M22 hex heads grabbed perfectly with a standard socket. The class 8.8 steel feels solid, and the 120mm length gave just enough thread to secure everything without bottoming out.

The partially threaded design made seating these in my equipment frame much quicker than fully threaded bolts. The hex heads held up perfectly under my impact wrench without any rounding.

I needed some heavy-duty fasteners for a jig I’m building, and these M22 cap screws fit the bill—the partially threaded design lets me get a solid grip without bottoming out on the nut. The hex head took my socket wrench without slipping, which made installation pretty straightforward.
