18-8 stainless steel screws have good chemical resistance.

These steel screws are zinc plated to resist corrosion in wet environments.

These metric screws have a triangular shank that presses tightly as it forms threads, so screws resist loosening in soft metals such as brass, aluminum, and copper.

Also known as Fastite screws, these offer more thread engagement in 0.028" to 0.063" thick sheets to prevent overtightening and damaging threads.
