18/8 or 18-8 Stainless steel is used primarily for long lasting applications, due to its corrosion-resistant nature and durability. Scratching or burring the metal will not create surface rust as the corrosion resistance exists within the metal itself. The corrosion resistant properties of stainless steel make Spanner Pan Head Machine Screws commonly seen in public areas where moisture is present.
