Professional Applications & Engineering Value
These hard fiber flat washers deliver critical engineering solutions where electrical insulation and thermal stability are paramount. The gray hard fiber material provides excellent dielectric properties, making them ideal for electrical assemblies, control panels, and electronic enclosures where current isolation is essential. Their vibration absorption capability prevents fastener loosening in machinery and automotive applications, while the temperature resistance up to 230°F ensures reliable performance in heated environments. The precise 0.094" ID and 0.25" OD dimensions, specifically engineered for No. 2 screws, eliminate fitment issues and reduce assembly time. These flat washers serve as essential components in applications requiring both mechanical spacing and electrical safety.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 0.094" inner diameter, 0.25" outer diameter, and controlled thickness between 0.014-0.016". Designed specifically for use with No. 2 screw size in inch measurement systems. These washers are RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting the latest environmental regulations for hazardous substances. The hard fiber material provides consistent performance across the specified temperature range while maintaining dimensional stability and insulation properties.
