S-92150A116 0.89" ID x 1.5" OD NAS1515-H14H Mil. Spec. Plastic Washers

Key Features & Benefits at a Glance

• Excellent corrosion resistance with non-metallic nylon construction, ideal for harsh environments where metal washers would degrade
• Superior electrical insulation properties prevent galvanic corrosion and electrical shorts in sensitive assemblies
• Precise dimensional fit with 0.89" ID and 1.5" OD ensures optimal load distribution for 7/8" screws
• Vibration and noise dampening characteristics protect fastened components from loosening and wear
• Lightweight and durable plastic construction reduces overall assembly weight without sacrificing performance
• Broad thermal compatibility with a maximum temperature rating of 180°F for various industrial applications
• Full regulatory compliance with RoHS 3 and REACH standards, ensuring safe and sustainable material usage

Professional Applications & Engineering Value

This NAS1515-H14H certified nylon flat washer delivers critical engineering solutions where metal fasteners fall short. Its white plastic construction provides inherent resistance to chemicals, oxidation, and electrical conductivity, making it indispensable in electrical enclosures, marine equipment, and food processing machinery. The precise 0.89" inner diameter and 1.5" outer diameter create an optimal bearing surface that prevents embedment into soft materials while distributing clamp load evenly for 7/8" screw applications. With a temperature range up to 180°F, this washer maintains dimensional stability in environments where thermal cycling would compromise metallic alternatives, offering reliable performance in automotive, aerospace, and industrial assembly contexts.

Specification Summary & Compliance

This flat washer conforms to NAS1515-H14H specifications with dimensional accuracy maintained through precision manufacturing. Critical measurements include 0.89" ID, 1.5" OD, and 0.084-0.104" thickness range for consistent performance with 7/8" screw sizes. The product demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to stringent environmental and safety standards for industrial components.
