• Reliable performance in inch-system assemblies requiring corrosion-resistant components

Professional Applications & Engineering Value

These silicon bronze flat washers deliver critical corrosion protection in demanding applications where standard steel components would rapidly deteriorate. The copper alloy composition provides inherent resistance to saltwater, chemicals, and atmospheric exposure, making them ideal for marine hardware, chemical processing equipment, and coastal infrastructure. The precise 0.26" inner diameter ensures perfect compatibility with 1/4" screws while the 0.688" outer diameter offers optimal load distribution surface. This combination solves common industrial pain points of fastener failure in corrosive environments, extending service life and reducing maintenance frequency in critical assemblies where reliability cannot be compromised.

Specification Summary & Compliance

Manufactured to inch-system dimensional standards with 0.26" ID, 0.688" OD, and 0.033-0.047" thickness range specifically engineered for 1/4" screw applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, including the latest SVHC requirements. The silicon bronze material provides consistent performance without additional surface treatments, meeting industrial requirements for corrosion-resistant fastening solutions in regulated environments.
