M22-2.5 X 200mm 六角頭螺絲 | 等級 10.9 鋼 原色 | 部分螺紋 (6 個/包)

Installed these on a heavy-duty press yesterday and the 200mm length gave me just enough grip for the thick flanges. The hex head seated perfectly in my socket without any wobble. Solid feel right out of the package.

The partial threading made these bolts work perfectly for my machinery repair, and the hex head let my socket grip them securely without slipping. They feel solid and well-made for the price.

I needed to replace some old bolts and these M22s fit perfectly—the partial thread gave me just enough grip without needing full shank engagement. They torqued down evenly without any galling, and the black oxide finish looks clean.
