- Inch system compatibility simplifies integration with standard North American equipment and fastening systems.
Professional Applications & Engineering Value
Engineered for demanding industrial applications, these 82° countersunk washers solve critical flush-mounting challenges where surface protrusion is unacceptable. The 18-8 stainless steel construction provides exceptional corrosion resistance for outdoor equipment, marine hardware, and chemical processing installations. With precise 0.156" ID and 0.562" OD dimensions, they ensure perfect alignment with No. 6 screws while the controlled 0.097-0.117" thickness maintains consistent clamping force in automotive assemblies, electronic enclosures, and precision machinery. The Rockwell B83 hardness prevents galling and maintains thread integrity through repeated installation cycles.
Specification Summary & Compliance
