S-93661A123 0.531" ID x 1.062" OD SAE Washers

Key Features & Benefits at a Glance

• Superior electrical and thermal conductivity for reliable performance in grounding and heat transfer applications
• Excellent corrosion resistance ensuring long-term durability in humid or chemically aggressive environments
• Precise SAE dimensional compliance with 0.531" ID and 1.062" OD for perfect fit with 1/2" fasteners
• Optimal load distribution through controlled thickness (0.074-0.121") to prevent surface damage and loosening
• Environmental regulation compliance meeting RoHS 3 and REACH standards for global supply chain acceptance
• Maintenance-free operation due to copper's natural anti-galling and non-sparking properties
• Broad industrial compatibility with inch-system components in electrical and mechanical assemblies

Professional Applications & Engineering Value

This copper flat washer delivers critical performance advantages in demanding industrial settings where electrical conductivity and corrosion resistance are paramount. The SAE standard design ensures dimensional interoperability with existing 1/2" screw fastening systems, while the pure copper material prevents galvanic corrosion when mating with dissimilar metals. Engineers specify these washers for electrical grounding applications, transformer connections, and plumbing systems where the material's malleability creates superior seals against fluid leakage. The combination of precise inch system dimensions and inherent corrosion resistance solves common failure points in industrial maintenance, reducing downtime and replacement costs in harsh operating environments.

Specification Summary & Compliance

Manufactured to SAE standards with precise dimensional tolerances: 0.531" inner diameter, 1.062" outer diameter, and thickness ranging 0.074-0.121" for consistent performance. The copper flat washer is engineered for compatibility with 1/2" screw size fasteners in inch-based assembly systems. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures unrestricted use in global markets and sensitive applications.
