• Exceptional Durability: Made from iron with Rockwell C35 hardness, this washer resists deformation and maintains integrity under high mechanical stress and repetitive loads.
• Precision Fit for Secure Fastening: With a 1.625" inner diameter designed specifically for 1 1/2" screw sizes, it provides a snug, reliable fit that minimizes loosening in industrial applications.
• Robust Construction for Demanding Environments: The 3" width offers a larger bearing surface, enhancing stability and vibration resistance in machinery and structural setups.
• Compliance with Global Standards: Meets RoHS 3 and REACH regulations, ensuring safety and environmental responsibility without compromising performance.
• Optimized for Inch System Applications: Manufactured to inch measurement standards, it ensures compatibility with existing tools and components, streamlining installation and maintenance.
• Long-Term Reliability: The combination of high-hardness iron and tapered geometry extends service life, reducing replacement frequency and maintenance costs.

Professional Applications & Engineering Value

This tapered washer is engineered to address common challenges in industrial fastening, such as uneven load distribution and joint failure. Constructed from iron with Rockwell C35 hardness, it provides excellent resistance to wear and compression, making it ideal for high-stress environments like construction machinery, automotive assemblies, and heavy equipment. The tapered profile (from 0.81" to 0.31" thickness) allows for gradual pressure absorption, which helps prevent bolt loosening and material fatigue in dynamic applications. By incorporating a 1.625" ID and 3" width, it ensures precise alignment with 1 1/2" screw sizes, enhancing assembly accuracy and reducing installation errors. This design not only improves safety and performance but also supports efficient maintenance cycles in sectors requiring reliable, long-lasting components.
