Stainless Steel (SS) plain washers are flat, circular rings made from corrosion-resistant steel (typically AISI 304 or 316), designed to distribute fastener load, protect surfaces from damage, and cover oversized holes. They are essential for reducing contact stress, preventing loosening, and providing a smooth bearing surface for bolts and nuts in industrial, marine, and construction applications.

Key Description and Characteristics:
Material: Usually 304 (A2) for general, excellent corrosion resistance, or 316 (A4) for higher corrosion resistance, including marine environments.
Shape: Flat, thin disc with a central hole, often with an outside diameter (OD) approximately twice the inside diameter (ID).
Purpose: Distributes pressure, prevents surface deformation (especially on soft materials), covers large clearance holes, and acts as a spacer.
Standards: Commonly adhere to DIN 125, ISO 7089, or IS 2016 standards.
Sizes: Metric sizes range from small (M2-M6) to large (M64 and above).
Finish: Usually bright/buff polished or passivated.
