M3.5-0.6 x 18mm 機械螺絲 | 平頭十字驅動 | 18/8不鏽鋼 (1,200顆/包)

Bought these for a washdown station rebuild and the 18/8 stainless is holding up great so far—no rust spotting after weeks of constant moisture. The 1,200 count means I've got plenty left over for future projects, which is a nice bonus.

Used a handful so far to mount electrical box covers in a damp basement, and the 18/8 stainless steel shows zero rust after a week of high humidity. The flat head design sits flush against the surface, which is exactly what I needed for a clean finish. For the price, having 1,200 solid machine screw

Honestly, the fact that these are non-magnetic sealed the deal for me—no more chasing stray screws around the workbench. Sorted through the whole 1,200 pack without finding a single bent thread, and the phillips head catches the driver bit perfectly every time.
