A stainless steel (SS) plain washer is a flat, round washer used with a machine threaded fastener and nut to distribute the load over a greater surface area, which helps prevent damage and wear to the surface material. They are widely available in various sizes and grades, such as SS 304 and SS 316, offering good corrosion resistance. Key Features and Applications

• Load Distribution: The primary function is to spread the clamping force of a bolt or screw, especially over soft materials or oversized/slotted holes.
• Corrosion Resistance: Made from stainless steel, these washers are rust-resistant and suitable for use in many environments, including marine, chemical, and food applications.
• Material Grades: Commonly available grades include SS 304 (A2) for general use and SS 316 (A4) for increased corrosion resistance, particularly in harsh or saltwater environments.
• Standards: They are often manufactured according to international standards such as DIN 125, IS 2016, and ISO 7089, which define specific dimensions for inner diameter (ID), outer diameter (OD), and thickness.
