S-90333A007 0.18" ID x 0.5" OD Finishing Washers

Key Features & Benefits at a Glance

• Superior Seating & Load Distribution: The integrated flange provides a wider bearing surface, reducing surface pressure and preventing pull-through in softer materials.
• Flawless Flush Finishes: The precise 82° countersink angle ensures a smooth, low-profile finish when used with standard countersunk screws, enhancing aesthetics and safety.
• Exceptional Corrosion Resistance: Manufactured from 18-8 Stainless Steel, this washer offers excellent durability and long-term performance in humid, chemical, or outdoor environments.
• Optimized for No. 6 Screws: The 0.18" ID provides a precise fit for No. 6 fasteners, ensuring secure placement and minimizing assembly play or misalignment.
• Robust Design for Demanding Applications: The combination of a 0.5" OD and flanged design increases structural integrity, making it ideal for high-vibration or high-stress assemblies.
• Guaranteed Material Compliance: Meets RoHS 3 and REACH regulations, ensuring safety and environmental responsibility for your global supply chain.

Professional Applications & Engineering Value

This 82° countersunk flanged washer is engineered to solve critical challenges in precision assembly. The 18-8 Stainless Steel construction provides inherent corrosion resistance, eliminating failure points in demanding environments like marine, food processing, or architectural metalwork. The flanged design is a key engineering advantage, distributing clamp load over a wider area to prevent damage to soft substrates like composites or aluminum. This is critical for maintaining joint integrity under vibration and thermal cycling. Paired with the standard 82° countersink angle for No. 6 screws, it ensures a perfectly flush mount, reducing snag hazards and achieving a clean, professional finish in visible applications. This component delivers reliable, long-term performance where fit, finish, and durability are non-negotiable.
