M6-1 X 65mm 內六角螺絲 | 六角驅動 | 部分螺紋 | 12.9級合金鋼鍍鋅 (200/包)

Used a full bag of these for a new set of tooling fixtures—the partially threaded shank gave me just the right grip length for tight clearance holes. They drove in cleanly without any cam-out, and the zinc finish feels robust enough for daily use on the press.

Installed these in a jig for a production run and the 65mm length was exactly what I needed. The threads are clean and the zinc plating gives them a nice uniform look.

Perfect fit for the 65mm depth I needed on a press fixture, and the zinc finish is holding up well in a humid shop. The hex socket drive made installation straightforward even in a tight spot.
