Professional Applications & Engineering Value
This nylon plastic flat washer delivers critical engineering advantages in demanding industrial environments where metal fasteners fall short. The nylon material provides inherent electrical insulation, making it ideal for electrical enclosures, control panels, and electronic assemblies where current isolation is paramount. Its broad temperature range from -40°F to 180°F ensures reliable performance in both freezing outdoor applications and heated industrial settings. The corrosion-resistant properties eliminate galvanic corrosion concerns when used with dissimilar metals, while the Rockwell R115 hardness maintains dimensional stability under compression loads. These flat washers are particularly valuable in automotive, marine, and outdoor equipment applications where environmental factors would compromise metal components.
Specification Summary & Compliance
This flat washer features precision inch system dimensions with 0.438" internal diameter and 0.625" outer diameter, specifically designed for 3/8" screw applications. The thickness is controlled between 0.026" to 0.036" for consistent performance. The washer is manufactured from nylon plastic with Rockwell R115 hardness rating and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring full regulatory compliance for industrial and commercial applications.
