S-90295A325 0.09" ID x 0.25" OD Plastic Washers

Key Features & Benefits at a Glance

• Corrosion-resistant nylon construction eliminates rust and galvanic corrosion in harsh environments
• Precise dimensional fit with 0.09" ID ensures secure seating on No. 2 screws without slippage
• Rockwell R115 hardness rating provides excellent resistance to deformation under load
• Wide temperature tolerance from -40°F to 180°F maintains performance in extreme conditions
• Lightweight plastic design reduces overall assembly weight without compromising strength
• RoHS 3 compliance meets stringent environmental regulations for global manufacturing
• Consistent 0.057-0.067" thickness ensures reliable spacing and uniform load distribution

Professional Applications & Engineering Value

These nylon plastic flat washers deliver critical engineering advantages where metal fasteners fail. The non-conductive, corrosion-resistant properties make them ideal for electrical assemblies, marine equipment, and chemical processing applications where galvanic corrosion must be prevented. With Rockwell R115 hardness, they maintain structural integrity under vibration and load, while the 0.25" OD provides sufficient bearing surface to prevent material embedding. The wide temperature range ensures consistent performance from freezer applications to industrial machinery operating at elevated temperatures, solving common failure points in thermal cycling environments.
