M7-1 x 16mm 六角頭螺絲 | 8.8級鋼鍍鋅 | 全牙 (300顆/包)

Put these on a heavy-duty jig I'm building and the hex drive seated perfectly without stripping. The 16mm length was just right for the metal flanges I'm bolting together. Packaging was also neat, with all 300 screws sorted in a sturdy box.

The zinc plating on these seems really consistent across all 300 screws, no bare spots or flaking off. I used a socket driver and the hex head seated perfectly without stripping. They’ve held up fine so far in my steel assembly project.

The hex drive on these M7-1 screws grips the socket perfectly without any slippage, even when I'm tightening them in tight spaces. The zinc plating looks consistently applied across all 300, which is nice for a cleaner finish on my assembly projects.
