M5 X 6mm 杯端內六角止付螺絲 | 合金鋼 鍍鋅 (1000入/包)

I needed a batch of set screws for a machinery adjustment project and these M5 cup points worked perfectly with my hex key. They feel solid, the zinc plating looks uniform, and the threading engaged smoothly without any stripping.

The cup point tip bit perfectly into my shaft collar without slipping, and the zinc coating looks clean. Needed a hundred for a project and got a thousand—won't run out soon. A solid buy for the price.

The hex socket drive made cinching these into a tight spot under the workbench way easier than fumbling with a wrench. A whole thousand of them in one box means I won’t be reordering for a long time, and the zinc plating looks clean and rust-free so far.
