S-91525A333 0.5" ID x 1.5" OD Oversized Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance provided by 316 stainless steel composition, ideal for harsh environments and chemical exposure
• Exceptional load distribution with 1.5" outer diameter creating a wider bearing surface for enhanced joint stability
• Precision dimensional accuracy with 0.5" inner diameter ensuring perfect fit for 7/16" screw applications
• Enhanced mechanical durability from Rockwell B68 hardness rating, resisting deformation under heavy loads
• Consistent thickness control (0.110-0.140") for uniform compression and reliable sealing performance
• Regulatory compliance assurance meeting both RoHS 3 and REACH standards for global industrial applications
• Long-term reliability in inch system assemblies with maintained performance across temperature variations

Professional Applications & Engineering Value

This 316 stainless steel flat washer delivers critical engineering solutions where corrosion resistance and structural integrity are paramount. The inch system compatibility ensures seamless integration with existing 7/16" fastener assemblies across marine, chemical processing, and food-grade applications. The optimized OD to ID ratio provides superior load distribution, preventing surface damage and maintaining bolt tension in high-vibration environments. Manufactured to precise thickness tolerances, these washers eliminate uneven clamping forces that compromise joint integrity. The Rockwell B68 hardness ensures dimensional stability under sustained pressure, while the 316 stainless steel composition resists pitting and crevice corrosion in chloride-exposed settings, significantly extending service life in demanding industrial applications.
