M3-0.5 X 22mm 機械螺絲 | 平頭一字槽 | 18/8 不鏽鋼 (900 / 包)

Used a bunch of these to fasten a custom electronics enclosure, and the slotted heads let me seat them flush with a standard screwdriver. The 22mm length was just right for my application, and the stainless finish feels solid.

Finally found slotted flatheads in 304 stainless at this length—perfect for vintage hardware restorations where you need the original look. The 22mm length worked well for my project, and the pack of 900 will last me years.

Had to replace some rusted screws on a marine railing, and these slotted heads sit perfectly flush. The non-magnetic 304 stainless is exactly what I needed for the salt air.
