David ★★★★★

Was pleasantly surprised by how well the slotted drive grips a standard screwdriver without stripping—these are noticeably tougher than the zinc-plated ones I've used before. Exactly right for securing a small bracket on my patio furniture where rust would be a problem.

Daniel Z. ★★★★★

Needed a small, strong screw for mounting metal brackets on outdoor equipment, and these stainless ones handled the damp weather without any rust. The slotted truss head let me get a good grip with a standard screwdriver, and a full 400-pack means I won't run out for a while.

Jacob O. ★★★★★

The truss head sits nice and flush on thin brackets, and the 18/8 stainless holds up perfectly in my damp garage without any rust after a month.
