S-92856A101 0.219" ID x 1.5" OD Dished Washers

Key Features & Benefits at a Glance

• Superior oversized hole compensation with 1.5" outer diameter for enhanced load distribution and prevention of fastener pull-through
• Exceptional corrosion resistance through zinc-plated steel construction for long-lasting performance in harsh industrial environments
• Optimized material hardness at Rockwell B40 ensures consistent clamping force and resistance to deformation under pressure
• Precision dimensional control with 0.438" diameter cup design provides secure seating for No. 10 screws in oversized applications
• Comprehensive regulatory compliance with RoHS 3 and REACH standards for safe use across global industrial markets
• Versatile thickness range from 0.030" to 0.065" accommodates various gap requirements while maintaining structural integrity
• Reliable inch system compatibility ensures seamless integration with standard industrial equipment and replacement parts

Professional Applications & Engineering Value

This heavy-duty cup washer addresses critical engineering challenges in oversized hole applications where standard washers fail to provide adequate bearing surface. The zinc-plated steel construction combines corrosion protection with mechanical strength, while the precisely engineered cup profile creates a secure mounting platform that prevents fastener loosening due to vibration or thermal cycling. The 0.438" diameter and 1.5" OD design effectively bridges gap tolerances in structural assemblies, electrical enclosures, and machinery frames where hole wear or manufacturing variances occur. Engineered for No. 10 screw installations, this washer maintains joint integrity in high-vibration environments common in automotive, construction, and industrial equipment applications.
