Stainless Steel Type 316 Flat Washers (for B8M Bolting)

The Stainless Steel Type 316 Flat Washer is an essential component for any flanged joint using ASTM A193 Grade B8M stud bolts and A194 Grade 8M nuts. Its primary function is to distribute the clamping load evenly across the joint surface, preventing damage to the flange material and ensuring the preload is maintained. Manufactured from AISI Type 316 stainless steel, these washers share the superior corrosion resistance of the mating fasteners, making them suitable for severe environments including those with chlorides and high temperatures. Zeron Fasteners supplies these flat washers in various dimensional standards (e.g., ASME B18.21.1 and DIN) and thicknesses, ensuring the integrity and longevity of critical bolted joints in the chemical and energy sectors.
