M14-2 X 30mm 六角頭螺絲 | Class 8.8 鋼 鍍鋅 | 全螺紋 (50 個/包)

Bought these for a machinery repair job and the 12.9 zinc coating held up tight even with an impact wrench. Thread depth was consistent across all fifty, no binding.

Threads were clean and uniform all the way down, so they seated perfectly in my machine frame without any binding. The zinc coating’s holding up fine after a few days of shop use, and the 50-count pack means I've got spares for the next job. Solid feel to the hex heads, too.

The hex head on these cap screws gave my socket wrench a solid grip, and the zinc plating looks clean and even. Worked perfectly for securing a heavy steel bracket on my workshop press.
