S-91717A221 6.4 mm ID x 17 mm OD Clipped Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in humid or outdoor environments
• Secure anti-rotation performance due to the clipped design with 14.4mm width, preventing loosening under vibration
• Enhanced load distribution from the 17mm outer diameter, reducing surface pressure and material deformation
• Precise M6 screw compatibility with 6.4mm inner diameter, ensuring easy installation and reliable fit
• Exceptional mechanical durability backed by Rockwell B55 hardness, resisting deformation under high-stress conditions
• Consistent thickness control (1.4-1.8mm) for uniform clamping force and assembly reliability
• Global regulatory compliance with RoHS 3 and REACH standards, ensuring safe use in international supply chains

Professional Applications & Engineering Value

Engineered for demanding industrial washers applications, these zinc-plated steel clipped washers solve critical vibration-induced loosening and corrosion issues in automotive assemblies, machinery, and mechanical systems. The clipped design provides positive locking against rotation, while the metric dimensions ensure compatibility with standard M6 fasteners. The zinc plating offers sacrificial protection against rust, making these heavy-duty washers ideal for outdoor equipment, electrical enclosures, and production lines where moisture and dynamic loads are present. Their precision manufacturing guarantees consistent performance in high-volume automated installations.
