Serrated Washers – AISI316

The serrated washer, made of AISI 316 stainless steel, ensures reliable grounding and mechanical fastening in harsh industrial and offshore environments. Its internal teeth bite into metal surfaces, enhancing conductivity and preventing loosening caused by vibration.

Made from acid-resistant stainless steel (EN 1.4401), this washer offers long-lasting performance in corrosive atmospheres, including marine and chemical processing applications. It is typically used with cable glands and lock nuts to maintain electrical continuity and mechanical stability.
