Stainless Steel Socket Cap Screws in this selection are made from grade 304 Stainless Steel. 304 Stainless Steel is often used interchangeably with 18-8 Stainless Steel in the fastener industry, because this grade is the standard for corrosion and rust resistance. We recommend using 304/18-8 Stainless Steel for applications exposed to fresh water moisture or weather, but upgrading to 316 Stainless Steel fasteners when the application will be exposed to salt water.
