S-90107A029 0.281" ID x 0.625" OD General Purpose Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 stainless steel construction
• Precise fit and reliable performance with a 0.281" inner diameter designed specifically for 1/4" screws
• Optimal load distribution and surface protection from the 0.625" outer diameter and flat profile
• Consistent spacing and vibration resistance ensured by the controlled 0.043-0.057" thickness range
• Long-term durability and material integrity in demanding industrial settings
• Global regulatory compliance with RoHS 3 and REACH standards for safe, responsible sourcing
• Versatile inch-system compatibility for seamless integration into existing assemblies and designs

Professional Applications & Engineering Value

These 316 stainless steel flat washers deliver exceptional value in corrosive or high-moisture applications where standard fasteners fail. The inch-system dimensions (0.281" ID, 0.625" OD) provide precise alignment with 1/4" screws, preventing loosening under vibration and distributing clamp load effectively to protect sensitive surfaces. The 316 grade stainless steel offers superior pitting and crevice corrosion resistance compared to lower grades, making these flat washers ideal for marine, chemical processing, food equipment, and outdoor infrastructure. Their consistent 0.043-0.057" thickness ensures reliable performance in industrial assembly lines, maintaining joint integrity while complying with stringent environmental regulations.
