Eli T. ★★★★★

I was a little worried about slotted drive screws being annoying, but these have clean, deep slots that grab the screwdriver without slipping. The 18/8 stainless finish is spotless and they’re genuinely non-magnetic, which I tested with a magnet just out of curiosity. Two hundred of them for this pr

Penelope ★★★★★

The truss head on these screws sits flush and looks clean, and the stainless steel feels solid. My only small note is that the slot is a bit shallow, but they still drive well with a standard flathead.

Mia C. ★★★★★

Needed some countersunk machine screws for a small outdoor project, and these truss heads fit perfectly with the stainless steel 18/8 build. The 5/16-18 threads behave exactly as expected, no stripping or wobble during install.
