M2.5-0.45 x 6mm 機械螺絲 | 圓頭十字槽 | 316不鏽鋼 (1,500顆/包)

These little screws are holding up perfectly on my outdoor saltwater aquarium setup. The 316 stainless steel gives me real peace of mind that they won't rust, even with constant splashing. For the price you get a ton of them too.

I grabbed these for a boat railing repair and the fact they're non-magnetic was a nice surprise for a stainless screw. Pan heads seated flush in the aluminum without any issue, and the corrosion resistance is exactly what I needed for the marine environment.

Used a handful for a saltwater aquarium light mount—no rust after three weeks, so the 316 stainless is legit. The Phillips heads didn’t strip even when I got a bit aggressive with the driver.
