M5-0.8 X 18mm 機械螺絲 | 平頭一字槽 | 18/8 不鏽鋼 (400 顆/包)

I needed a batch of fasteners that wouldn't rust on a boat repair, and these slotted 18/8 stainless screws fit perfectly and don't strip as easily as some cheaper ones. The flat heads sit flush in the countersunk holes, which made for a clean finish. Great value for the quantity.

The slot cut is clean and deep, so the driver doesn’t slip even when I’m torquing them down in tight spots. I’ve got them holding a gate hinge outside, and after a few weeks of rain, there’s zero rust. For four hundred pieces, the price feels more than fair.

Used these to fasten a stainless steel drip tray onto my grill cart and the flat heads sit perfectly flush. The 304 stainless holds up great outdoors with no rust so far. Pack of 400 is way more than I needed for that one job.
