Professional Applications & Engineering Value
This fiberglass flat washer delivers critical engineering solutions where conventional metal washers fail. The fiberglass material provides excellent electrical insulation and corrosion resistance, making it ideal for electrical enclosures, power distribution systems, and marine applications. With a maximum temperature rating of 280°F, it maintains structural integrity in high-heat environments like engine compartments, industrial ovens, and HVAC systems. The Rockwell M100 hardness ensures the washer withstands compression forces without deformation, while the precise 0.5" ID provides optimal fit for 1/2" screw sizes in critical assembly operations. These properties make it particularly valuable in industries requiring non-conductive, heat-resistant fastening solutions that comply with stringent safety regulations.
Specification Summary & Compliance
This inch-system flat washer features precise dimensions of 0.5" inner diameter and 2" outer diameter with thickness ranging from 0.108" to 0.142". Manufactured to exacting standards for use with 1/2" screw sizes, it maintains consistent dimensional accuracy. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant (including 223 SVHC as of 01/17/2022), ensuring environmental safety and regulatory adherence for industrial applications worldwide.
