M5-0.8 X 65mm 六角帽螺絲 | 平頭六角驅動 | 部分螺紋 | 12.9 級合金鋼 鍍鋅 (100 入)

The partially threaded design made them perfect for holding tight in my metal tooling setup while leaving room for spacers. They drive in smoothly with a hex key and feel incredibly strong—no stripping even under heavy torque.

Used these to build a custom jig for my drill press and the partial threading made alignment much easier. Each screw seated perfectly without any stripping, and the zinc plating has held up well under light use. Exactly what I needed for precision assembly work.

The 12.9 grade alloy steel feels extremely rigid and quality—way tougher than the standard hardware I’ve been using for my tooling fixtures. These partially threaded M5 screws hold perfectly in a press jig without any wobble. Exactly what I needed for precision assemblies.
