S-92916A181 0.31" ID x 0.875" OD Oversized Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance from high-quality brass material, ideal for humid or chemically exposed environments
• Precise dimensional fit with 0.31" ID and 0.875" OD ensuring perfect alignment with 1/4" screws
• Enhanced load distribution and surface protection due to controlled thickness range (0.041-0.061")
• Excellent mechanical durability provided by Rockwell B60 hardness for long service life under stress
• Full regulatory compliance with RoHS 3 and REACH standards, meeting strict industrial safety requirements
• Reliable performance in inch system applications, compatible with standard US hardware and equipment
• Reduced maintenance needs thanks to brass's natural anti-galling and non-sparking properties

Professional Applications & Engineering Value

These brass flat washers deliver critical engineering solutions where corrosion resistance and electrical conductivity are paramount. Made from durable brass material, they prevent galvanic corrosion when used with dissimilar metals and maintain integrity in marine, plumbing, and electrical applications. The precise 0.31" inner diameter ensures secure fit on 1/4" screws, while the 0.875" outer diameter provides optimal load distribution across fastened surfaces. With Rockwell B60 hardness, these washers withstand repeated assembly/disassembly cycles without deformation, making them ideal for maintenance-heavy industrial equipment, automotive assemblies, and precision instrumentation where reliability cannot be compromised.
