S-91153A036 0.813" ID x 3" OD Beveled Washers

Key Features & Benefits at a Glance

• Exceptional Load Distribution with a large 3" outer diameter that minimizes surface pressure and prevents material damage in heavy-duty applications
• Secure Anti-Rotation Performance thanks to the notched design that prevents washer movement under vibration and dynamic loads
• Superior Durability achieved through Rockwell B62 hardness iron construction, resisting deformation under extreme pressure
• Precision Fit for 3/4" Fasteners with 0.813" inner diameter ensuring proper alignment and optimal clamping force distribution
• Enhanced Structural Integrity from the substantial 0.438" thickness that maintains stability in high-stress environments
• Environmental Compliance Assurance meeting RoHS 3 and REACH standards for safe use across regulated industries
• Long-Term Corrosion Resistance through iron material properties that maintain performance in demanding conditions

Professional Applications & Engineering Value

This heavy-duty notched washer delivers critical engineering solutions where standard washers fail. The iron construction with Rockwell B62 hardness provides exceptional resistance to deformation under extreme compressive loads, making it ideal for structural applications in construction, heavy machinery, and industrial equipment. The notched design specifically addresses vibration-induced loosening in dynamic environments, ensuring maintained clamping force in automotive assemblies, agricultural equipment, and infrastructure projects. With precise 3/4" screw compatibility and substantial 3" OD surface coverage, this washer prevents embedment in softer materials while distributing loads effectively across larger areas. The combination of 0.438" thickness and material strength makes it particularly valuable in applications requiring repeated disassembly and reassembly without performance degradation.
