Product Description

316 stainless steel hex nuts are made from 316 stainless steel, an austenitic alloy which differs from 18-8 by its molybdenum content (2-3%) and a higher nickel content (10-14%). Dimensional specifications are governed by ASME B18.2.2 for finish nuts, and ASME B18.6.3 for the smaller diameter machine nuts. Nuts made of 316 stainless steel are marked “316”. 316 stainless steel fasteners are commonly used in applications that require general atmospheric corrosion resistance, such as chemical and food processing equipment. More corrosion resistant than 18-8 stainless steel nuts.
