Grade 2: A finished hex nut made of low carbon steel. Grade-2 nuts are for use with any low carbon bolt or screw that is not heat-treated, with a specified minimum tensile strength of 74,000 psi or less.
Grade 5: A finished hex nut made from steel with a maximum carbon content of 0.55%. Grade-5 nuts are for use with bolts with a minimum tensile strength equal to or less than the specified proof stress of the nut.
Grade 8: A finished hex nut made from steel with the same maximum carbon content as a Grade-5 nut. Designed for use with bolts with a minimum tensile strength equal to or less than 150,000 psi.
Grade-9, EcoGuard Gray/Silver Finish (Thick Hex): A thick hex nut made from steel with a maximum carbon content of 0.55%. Grade-9 nuts are thicker than heavy hex nuts of the same nominal size. For use with bolts with a minimum tensile strength equal to or less than 180,000 psi. Offered in a coarse and fine thread and they are U.S.A made.
Stainless: A finished hex nut made of 18-8 stainless steel (303 & 304 series) & 316. Designed for use with stainless steel bolts and screws with a specified minimum tensile strength equal to or less than the specified proof stress of the mating nut. Both types of stainless are corrosion resistant with 316 stainless having greater such resistance as well as superior strength at raised temperatures.
