M20-1.5 X 100mm 六角頭螺絲 | 8.8 級鋼鍍鋅 | 部分螺紋 (20 入/包)

The partial threads grabbed perfectly when I mounted these on my press frame—no cross-threading at all, even with a socket wrench. Zinc coating looks uniform and should hold up fine in the shop.

Used these to bolt down a heavy-duty workbench leg bracket, and the 8.8 steel held tight under a lot of torque without stripping. The partial threading made it much easier to start the nut by hand.

The zinc plating on these M20 screws looks tough and even, which is exactly what I needed for outdoor equipment assembly. The hex head gave my socket wrench a solid grip without any slipping. These are holding up great so far.
