S-92303A108 0.531" ID x 2" OD Oversized Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Exceptional load distribution from the 2" outer diameter, minimizing surface pressure and material fatigue
• Precise screw alignment ensured by the 0.531" inner diameter, perfectly matching 1/2" fasteners
• Enhanced mechanical durability with Rockwell B83 hardness, resisting deformation under heavy loads
• Consistent performance maintained through controlled thickness (0.235-0.265") for uniform clamping force
• Environmental compliance with RoHS 3 and REACH standards, safe for regulated industries
• Long-term reliability in inch-system applications, reducing maintenance and replacement frequency

Professional Applications & Engineering Value

This 18-8 stainless steel flat washer delivers critical engineering solutions where corrosion resistance and structural integrity are paramount. The optimized 2" OD provides superior surface coverage, preventing joint loosening in vibrating equipment and distributing load stress effectively across assemblies. With precise 0.531" ID matching standard 1/2" screws, it eliminates misalignment issues in machinery, construction, and marine applications. The Rockwell B83 hardness ensures the washer maintains its form under sustained pressure, while the inch-system dimensions guarantee compatibility with North American industrial equipment. These flat washers are engineered to withstand chemical exposure, moisture, and temperature variations, making them ideal for heavy-duty applications in manufacturing plants, infrastructure projects, and offshore installations.

Specification Summary & Compliance
