M5-0.8 X 20mm 機器螺絲 | 圓頭一字槽 | 鋼鍍鋅 (900 個/包)

The zinc plating on these looks even and clean, which is exactly what I needed for some light outdoor repairs without worrying about rust. The 20mm length threads smoothly into M5 nuts without any binding, and having 900 of them means I probably won't need to order again for years.

Needed a bulk supply for a handful of furniture assembly projects, and these cheese head screws worked perfectly with a standard slotted driver. The zinc plating seems evenly applied with no rough edges, which was a pleasant surprise at this price point.

Put together a couple of small jigs for the workshop and these screws were perfect. The zinc coating gives them a clean, uniform look and I had zero issues with the slotted drive on a hand driver.
