ASTM F436 Type 304 Stainless Steel Washers

The ASTM F436 Type 304 Washer is a crucial component in high-integrity bolting assemblies, designed to be paired with ASTM A193 B8 Stud Bolts and ASTM A194 Grade 8 Nuts. While not always chemically mandatory, using a washer made of stainless steel (Grade 304) is essential in corrosive and high-temperature environments to ensure material compatibility. These hardened washers serve several critical functions: they distribute the fastener's load more evenly over the surface area, prevent damage or embedment of the nut/bolt head into the flange material, and bridge oversized bolt holes. Zeron Fasteners supplies these quality washers, ensuring they meet the dimensional and mechanical specifications required for reliable and safe use in petrochemical, power, and industrial piping systems.
