SPECIFICATIONS
316 Stainless Steel offers superior corrosion resistance when compared to standard grade, 18-8 and 304 type stainless steels. Suitable for harsh environmental conditions including salt water exposure (docs, marinas and boats). Stainless Steel Grade 316 contains the same amount of chromium as 304 (18-8 commonly referred to as), but with a higher percentage of nickel plus 2-3% molybdenum. Molybdenum increases the metalâ„¢s resistance to salt, making it perfect for the most corrosive environments. Typically, this is the metal used in marine applications. Used in applications where protrusion of the fastener above the mating surface is unacceptable. Use a protrusion gage when measuring head height. A countersunk head with a flat top surface and a cone-shaped bearing surface with a head angle of approximately 82 degrees.
