S-98019A502 0.469" ID x 0.922" OD MS15795-816; NASM15795; ASME B18.21.1 Mil. Spec. Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance through passivated 18-8 stainless steel construction, extending service life in harsh environments
• Precise dimensional fit with 0.469" ID and 0.922" OD ensuring optimal load distribution for 7/16" fasteners
• Enhanced mechanical durability with Rockwell B70 hardness for reliable performance under repeated stress
• Rigorous quality assurance through compliance with MS15795-816, NASM15795, and ASME B18.21.1 standards
• Environmental responsibility with full RoHS 3 and REACH compliance for global industrial applications
• Consistent thickness control (0.051-0.080") for uniform clamping force and vibration resistance
• Broad compatibility with inch-system components across aerospace, marine, and industrial assemblies

Professional Applications & Engineering Value

Engineered for demanding environments, these passivated 18-8 stainless steel flat washers provide critical corrosion protection where moisture, chemicals, or salt exposure would degrade ordinary components. The precision 0.469" ID and 0.922" OD dimensions ensure perfect alignment with 7/16" screws, preventing bolt hole elongation and maintaining clamp load integrity in vibrating machinery. Meeting MS15795-816 and NASM15795 specifications, they deliver consistent performance in aerospace frames, marine hardware, and food processing equipment where material purity and Rockwell B70 hardness prevent deformation under high torque applications.

Specification Summary & Compliance

Manufactured to ASME B18.21.1 dimensional standards with inch-system precision. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, including the latest SVHC updates. Certifications cover MS15795-816 and NASM15795 aerospace standards for quality assurance in critical applications.
