S-95606A440 0.375" ID x 0.57" OD Plastic Washers

Key Features & Benefits at a Glance

• Exceptional temperature resilience for stable performance in environments ranging from -40°F to 180°F, preventing material degradation under thermal stress.
• Superior vibration and load distribution thanks to the precise 0.375" ID and 0.57" OD, ensuring secure seating for 5/16" screws and reducing loosening.
• Excellent electrical insulation and corrosion resistance inherent to Nylon Plastic, ideal for preventing galvanic corrosion in mixed-material assemblies.
• Consistent mechanical strength with Rockwell R115 hardness, providing reliable surface protection and extended service life under repeated tightening.
• Lightweight and non-magnetic properties for applications in electronics, aerospace, and marine industries where weight and interference are concerns.
• Compliance with RoHS 3 and REACH regulations, ensuring safe use in global markets without hazardous substances.
• Uniform thickness (0.026-0.036") for even pressure distribution, minimizing the risk of fastener fatigue and joint failure.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, this Nylon Plastic Flat Washer addresses critical challenges in assembly integrity and environmental exposure. Its temperature-resistant properties from -40°F to 180°F make it suitable for outdoor equipment, automotive components, and electrical enclosures where thermal cycling is common. The 5/16" screw size compatibility ensures a precise fit, reducing the risk of misalignment and enhancing load distribution. As a non-conductive and chemically inert material, it prevents electrical shorts and resists oils, solvents, and moisture, extending the lifespan of assemblies in harsh conditions. This washer is a reliable choice for engineers seeking durability and compliance in industrial washers without the weight of metal alternatives.
