Professional Applications & Engineering Value

Engineered for demanding industrial environments, these passivated 18-8 stainless steel flat washers provide critical protection against galvanic corrosion and chemical degradation. The precision inch-system dimensions (0.078" ID × 0.188" OD) ensure perfect alignment with No. 1 screw fasteners, eliminating play and distributing clamp load evenly to prevent surface marring and joint loosening. Ideal for aerospace assemblies, electronic enclosures, and marine equipment where MS15795-801/NASM15795 compliance is mandatory, these washers maintain dimensional stability under vibration and thermal cycling. The Rockwell B70 hardness provides exceptional resistance to deformation, while the passivated surface treatment creates a protective oxide layer that significantly extends service life in corrosive atmospheres.
