S-95606A410 0.25" ID x 0.375" OD Plastic Washers

Key Features & Benefits at a Glance

• Excellent corrosion resistance due to nylon plastic construction, ideal for harsh environments without risk of rust or chemical degradation.
• Reliable load distribution and vibration dampening with precise 0.25" ID and 0.375" OD, ensuring secure fit and reduced loosening for No. 12 screws.
• Consistent performance across extreme temperatures, operating reliably from -40°F to 180°F without cracking or deforming.
• Durable and wear-resistant with Rockwell R115 hardness, providing long service life under mechanical stress.
• Lightweight and non-conductive nylon material reduces overall assembly weight and prevents electrical conductivity issues.
• Full compliance with RoHS 3 and REACH standards, ensuring safe use in regulated industrial applications without hazardous substances.
• Precise thickness control (0.010-0.020") allows for uniform sealing and spacing in inch-based assembly systems.

Professional Applications & Engineering Value

This nylon plastic flat washer is engineered to address common industrial challenges such as corrosion, electrical isolation, and thermal stability. Made from high-grade nylon material, it provides inherent resistance to moisture, chemicals, and UV exposure, making it suitable for outdoor, marine, and chemical processing equipment. The flat washer design ensures even pressure distribution, preventing surface damage and screw loosening in vibrating machinery. With an operating range from -40°F to 180°F, it maintains integrity in both freezing and moderately high-temperature environments, such as automotive assemblies, electrical enclosures, and HVAC systems. Its Rockwell R115 hardness offers sufficient toughness for repeated use, while the precise 0.25" ID and 0.375" OD fit standard No. 12 screws, simplifying inventory and installation in inch system applications.

Specification Summary & Compliance

This washer meets standard dimensional tolerances for inch-based flat washers, with inner diameter of 0.25", outer diameter of 0.375", and thickness ranging from 0.010" to 0.020". It conforms to general industrial specifications for fit and function with No. 12 screw sizes. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for hazardous substance restrictions.
