what do the Stainless Steel Grdae mean?

Stainless steel fasteners are defined by the grade of the material. Now what exactly does this mean? See the list below for information on common grades of stainless steel fasteners including material and common applications. 

  • Type 304: 17%-19% Chrome, 8%-12% Nickel, .08% Maximum Carbon. This is a superior grade of 18-8 stainless steel and is used for Machine Screws, Cap Screws, Sheet Metal Screws, Hex Cap Screws and all cold headed or hot forged fasteners. It is an equivalent to 18-8 Stainless Steel.

  • Type 305: 17%-19% Chrome, 8%-10% Nickel, .12% Maximum Carbon. This grade has been developed specifically to improve the cold heading qualities of 18-8. This grade does not work hardened products are actually made from this grade even though they are referred to as being made from type 304 Corrosion resistance and physical qualities are equal to Type 304.

  • Type 316: 16%-18% Chrome, 10%-14% Nickel, .08% Maximum Carbon, 2.00% Maximum Molybdenum. This grade is greater corrosion resistance when used with certain acids as compared to general range of 18-8 stainless steel. 316 Stainless Steel is used in saltwater application such as boats and docks.

  • Type 18-8: 18% Chrome, 8% Nickel, .08% Maximum Carbon. Used in most fasteners and is the standard.It is an equivalent to 304 Stainless Steel.

  • Type 410: 11.5%-13.5% Chrome, .15% Maximum Carbon. This grade can be bright and hardened up to approximately 40 Rockwell C. This is used in roofing screws and finishing washers.
  •  Other Stainless steel Grade we have is, Type 317L, Type 347, Type 321, Type 310, Type 316L, Type 304L, Type 904L, Type A286 Gr. 660, Type Alloy 20
