S-91525A117 0.266" ID x 0.5" OD Oversized Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 stainless steel construction
• Precise fit for 1/4" screws with 0.266" ID ensuring secure fastening and load distribution
• Durable mechanical performance with consistent 0.5" OD and 0.043-0.057" thickness range
• Compliance with strict environmental regulations including RoHS 3 and REACH for global supply chain compatibility
• Ideal for inch-system applications in marine, chemical, and food processing industries
• Reliable surface protection for connected components, reducing galvanic corrosion risks

Professional Applications & Engineering Value

These 316 stainless steel flat washers deliver exceptional value in corrosive or high-moisture settings where standard fasteners fail. The inch-system dimensions (0.266" ID, 0.5" OD) ensure perfect compatibility with 1/4" screws, maintaining clamp load integrity under vibration. Engineers specify them for marine hardware, chemical processing equipment, and offshore structures where pitting resistance is critical. The controlled thickness (0.043-0.057") provides consistent bearing surface, preventing joint loosening while the RoHS 3 and REACH compliance supports sustainable manufacturing protocols without sacrificing performance.

Specification Summary & Compliance
