Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments including marine and chemical applications
- Precise dimensional fit for No. 10 screws with 0.203" ID and 0.5" OD, ensuring reliable load distribution and vibration resistance
- Consistent thickness tolerance (0.033-0.047") maintains uniform pressure distribution across fastened surfaces
- Full regulatory compliance with RoHS 3 and REACH standards, eliminating supply chain restrictions for global industrial projects
- Long-term durability in extreme conditions thanks to 316 stainless steel's exceptional pitting and crevice corrosion resistance
- Interchangeable compatibility with inch-system fasteners, simplifying maintenance and replacement in existing equipment
Professional Applications & Engineering Value
These 316 stainless steel flat washers deliver critical performance in demanding applications where corrosion threatens fastener integrity. The 0.203" ID provides precise alignment with No. 10 screw sizes while the 0.5" OD distributes clamping forces effectively across softer materials or painted surfaces. Engineered for industrial washers applications in chemical processing, marine hardware, and food equipment, the inch system washers maintain dimensional stability under thermal cycling and mechanical stress. The corrosion resistant washers prevent galvanic corrosion in mixed-material assemblies, extending service life while meeting stringent RoHS 3 and REACH compliant environmental standards for global manufacturing operations.
Specification Summary & Compliance
Manufactured to precise inch-system dimensions: 0.203" inner diameter, 0.5" outer diameter, with thickness ranging 0.033-0.047". These flat washers comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring unrestricted use in international markets. The 316 stainless steel composition provides inherent corrosion resistance without additional surface treatments, maintaining dimensional accuracy across temperature variations and mechanical loads.
