S-92917A146 0.228" ID x 0.5" OD General Purpose Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance from nickel-plated brass construction, extending service life in humid or chemically aggressive environments
• Precise dimensional fit with 0.228" ID and 0.5" OD ensures secure seating and uniform load distribution for No. 12 screws
• Consistent thickness range (0.030-0.050") provides reliable spacing and vibration dampening in assembled components
• Environmental compliance with RoHS 3 and REACH standards eliminates hazardous substance concerns in regulated industries
• Excellent electrical conductivity of brass maintains grounding integrity in electrical assemblies
• Durable plating resists wear during installation and maintains aesthetic appearance in visible applications
• Broad industrial compatibility with inch-system fasteners simplifies procurement and inventory management

Professional Applications & Engineering Value

These nickel-plated brass flat washers deliver critical performance advantages in demanding applications where corrosion resistance and electrical properties matter most. The brass core material provides inherent corrosion resistance while the nickel plating adds an extra protective layer against oxidation and chemical exposure. This combination proves invaluable in electrical enclosures, marine components, and plumbing systems where moisture and corrosive elements are present. The precise 0.228" ID ensures snug fitment on No. 12 screws, preventing misalignment and distributing clamp load effectively across the 0.5" OD surface. This dimensional accuracy prevents stress concentration points that could lead to material fatigue or joint failure over time, making these industrial flat washers reliable solutions for vibration-prone assemblies and critical fastening applications.

Specification Summary & Compliance

This flat washer features inch-system dimensions with 0.228" internal diameter, 0.500" outer diameter, and thickness ranging from 0.030" to 0.050" for compatibility with No. 12 screw size. Manufactured from nickel-plated brass for optimal performance, the product fully complies with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations regarding chemical safety. These compliance certifications ensure the washers meet international environmental standards for industrial applications.
