Henry ★★★★★

Bought these for a washdown station rebuild and the 304 stainless is holding up perfectly against the constant water exposure. The truss heads sit flush and the phillips drive grabs nicely without stripping. Pack of 100 was more than enough, so I've got spares for next time.

Joshua ★★★★★

The truss head sits nice and flush on my outdoor gate hinges, and the Phillips drive grabbed tight without stripping. I've had bad luck with other stainless screws rusting, but these 18/8 ones seem solid after a few weeks of rain.

David B. ★★★★★

These are exactly as spec'd, the 18/8 stainless is a solid choice for our outdoor gate hardware since they won't rust. The Phillips drive seated well with my driver bit, and the truss head gives a nice, low profile.
