Imperial Flat Washers Stainless

Flat Round Washers – Imperial Sizes, Stainless Steel

Imperial stainless steel flat round washers are precision-engineered components designed to evenly distribute the load of a fastener, reducing surface stress and preventing damage to the material beneath. Manufactured in imperial dimensions, these washers are ideal for use with UNC, UNF, and other inch-based fasteners commonly found in machinery, automotive, marine, and general engineering applications.

Made from high-grade stainless steel (304 or 316), these washers offer excellent resistance to corrosion, making them suitable for indoor and outdoor environments, including coastal and chemical-exposed areas. Their flat, smooth profile provides a clean bearing surface and helps maintain bolt tension under vibration or thermal expansion.

  • Available in standard imperial sizes (No. 4 to 1", and beyond)

  • Corrosion-resistant stainless steel for long-term durability

  • Ideal for marine, industrial, and engineering applications

  • Precision stamped for consistent thickness and fit

Whether you're restoring classic equipment or working on new builds with inch-based hardware, these imperial stainless steel flat washers ensure reliability, strength, and long-term performance in every assembly.
