S-93490A018 0.392" ID x 0.875" OD General Purpose Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance for extended service life in harsh environments, thanks to silicon bronze material composition
• Precise dimensional fit with 0.392" ID and 0.875" OD ensures optimal load distribution and secure fastening for 3/8" screws
• Consistent thickness control (0.055-0.069") provides reliable performance and uniform pressure distribution across applications
• Environmental compliance assurance with RoHS 3 and REACH compliance for safe use in regulated industries
• Excellent durability in marine and chemical exposures where standard steel washers would rapidly degrade
• Inch-system compatibility for seamless integration with existing North American equipment and fastener systems
• Non-sparking properties for enhanced safety in potentially explosive or flammable environments

Professional Applications & Engineering Value

These silicon bronze flat washers deliver critical engineering value in applications where corrosion resistance is paramount. The silicon bronze material provides exceptional protection against saltwater, chemicals, and atmospheric corrosion that would rapidly deteriorate standard steel washers. This makes them ideal for marine hardware, coastal construction, chemical processing equipment, and offshore installations. The precise 0.392" ID ensures perfect fitment for 3/8" screws, preventing misalignment and distributing load evenly across fastened surfaces. The controlled 0.055-0.069" thickness maintains consistent clamping force while the 0.875" OD provides ample bearing surface. These inch-system washers solve the critical problem of fastener failure in corrosive environments, significantly extending maintenance intervals and reducing total cost of ownership.
