Professional Applications & Engineering Value
This hard fiber flat washer is engineered to address common industrial challenges such as electrical short-circuiting and metal corrosion. Its gray hard fiber construction provides a robust, non-conductive barrier, making it indispensable in electrical enclosures, control panels, and electronic devices where insulation is critical. The material's inherent resistance to moisture and chemicals prevents degradation, extending the life of assemblies. Specifically designed for No. 4 screws in the inch system, it ensures a perfect fit, reducing installation errors and enhancing mechanical stability. By offering reliable performance up to 230°F, it supports applications in automotive, appliance, and general industrial sectors, delivering consistent value through improved safety and reduced maintenance.
Specification Summary & Compliance
This flat washer adheres to standard inch system dimensions with an Inside Diameter (ID) of 0.125", Outside Diameter (OD) of 0.25", and a controlled Thickness of 0.014-0.016", ensuring compatibility with No. 4 screw sizes. Manufactured from hard fiber, it is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances and supporting global supply chain requirements for industrial washers.
