M3-0.5 X 6mm 內六角圓頭螺絲 | 六角驅動 | 全牙 | 10.9級合金鋼鍍鋅 (1000顆/包)

The hex drive on these M3 screws grabs the bit perfectly, no stripping or cam-out at all. They’re a solid fit for tightening down small fixtures on my CNC machine.

The full threading made these perfect for a tight jig assembly I was working on, and the zinc plating looks consistent across all 1,000 pieces. One minor thing—a few screws had slightly uneven slots, but they seated fine with a hex key.

The hex socket drive on these M3 screws makes them easy to tighten without stripping, which is great for jig assembly. The zinc plating looks clean and they come well-packed in a sturdy box. Only wish the package had a resealable bag for long-term storage.
