S-90495A152 0.41" ID x 2" OD Oversized Washers

Key Features & Benefits at a Glance

• Exceptional load distribution with 2" outer diameter to prevent surface damage and maintain joint integrity under high stress
• Superior corrosion resistance through zinc yellow-chromate plating for extended service life in harsh industrial environments
• Maximum strength reliability with Grade 8 classification and Rockwell C38 hardness for heavy-duty applications
• Precise compatibility with 3/8" fasteners thanks to 0.41" inner diameter and inch system standardization
• Consistent performance ensured by controlled thickness (0.047-0.080") for uniform pressure distribution
• Environmental compliance meeting RoHS 3 and REACH standards for safe global industrial use
• Durable material construction using plated steel for optimal balance of strength and corrosion protection

Professional Applications & Engineering Value

These Grade 8 flat washers deliver critical engineering solutions where high-strength fastening systems face demanding conditions. The zinc yellow-chromate plated steel construction provides essential corrosion resistance against moisture, chemicals, and environmental exposure, significantly extending maintenance intervals in industrial equipment, structural assemblies, and heavy machinery. With Rockwell C38 hardness and Grade 8 classification, these washers maintain dimensional stability under extreme loads, preventing embedment and joint relaxation. The precise 3/8" ID ensures proper fastener alignment while the 2" OD distributes clamping force effectively across softer materials or painted surfaces. Ideal for construction, manufacturing, and automotive applications where heavy-duty performance and regulatory compliance are mandatory.
