براغي ماكينة M5-0.8 × 8 مم | رأس مسطح فيليبس | فولاذ مقاوم للصدأ 316 (400/عبوة)

Roughly a year in a damp coastal shed and not a speck of rust on these, which is exactly why I went with the 316 stainless. The pan head sits flush in my aluminum brackets and the Phillips drive doesn't strip when I'm torquing them in.

The threads are clean and catch evenly from the start, which made driving them into pre-tapped holes effortless. I grabbed these for a small boat repair project, and the 316 stainless gives me real peace of mind against saltwater corrosion.

Installed these on a dock railing that gets constant salt spray, and after three months there's not a hint of rust. The pan head sits flush and the Phillips drive doesn't cam out.
