• Consistent thickness control (0.022-0.028") for uniform pressure application and reduced assembly variability
• Enhanced durability with Rockwell C20 hardness providing excellent resistance to deformation under load
• Guaranteed specification compliance meeting MS51496-P63 standards for reliable interchangeability and quality assurance
• Environmental responsibility with full RoHS 3 and REACH compliance, safe for regulated industrial applications
• Optimized for industrial use in inch-system assemblies requiring corrosion-resistant, precision flat washers

Professional Applications & Engineering Value

These passivated 18-8 stainless steel flat washers deliver critical protection against galvanic corrosion and chemical exposure in demanding environments. The precise 0.099" ID x 0.161" OD dimensions ensure perfect alignment with No. 1 screws, preventing loosening and distributing clamp load effectively across sensitive components. Engineered to MS51496-P63 specifications, these washers maintain dimensional stability in high-vibration applications from electronics enclosures to precision instruments. The controlled 0.022-0.028" thickness provides consistent spacing while the Rockwell C20 hardness resists embedding in softer materials. Ideal for aerospace, medical device, and marine applications where corrosion-resistant washers must maintain integrity without contaminating sensitive assemblies.
