M6-1 X 80mm 內六角螺絲 | 圓頭內六角驅動 | 全螺紋 | 12.9級合金鋼鍍鋅 (100顆/包)

These are exactly the right length for the jig I was building, and the hex socket drives smoothly without stripping. The zinc plating looks clean and the threads cut perfectly into my fixtures. Beat the price of the local hardware store by a long shot.

The hex socket drive made installing these into my machinery jig much easier than using a standard allen key. The zinc plating seems solid and they threaded perfectly into the tapped holes I prepared.

I needed these for a jig I was building, and the full threading along the entire 80mm length made alignment a breeze. The zinc plating looks clean and should hold up fine in my shop.
