Sofia ★★★★★

I installed these in a damp outdoor planter box and they haven't shown a speck of rust after a month of rain. The 28mm length was perfect for securing the thicker cedar boards, and the slotted head gave a clean, traditional look.

Matthew ★★★★★

The flat head sits flush perfectly, and these slotted screws are a breeze to drive without stripping—the 18/8 stainless feels solid and the non-magnetic property is a nice plus. Six hundred in one pack means I'm set for a long while, and they handle my outdoor gear without a hint of rust so far.

Aurora ★★★★★

Needed these for a kitchen remodel where standard screws kept rusting near the sink. The 18/8 stainless steel is holding up perfectly in the damp environment, and the slotted head gives a classic look I actually prefer.
