S-91717A204 0.469" ID x 1.5" OD Clipped Washers

Key Features & Benefits at a Glance

• Enhanced corrosion resistance through black-oxide steel construction, extending service life in harsh environments.
• Secure and stable fastening with a precise 0.469" inner diameter designed for 7/16" screws, minimizing loosening.
• Superior load distribution thanks to the large 1.5" outer diameter, reducing surface pressure and material stress.
• Excellent durability and wear resistance provided by Rockwell B40 hardness, ensuring long-term reliability.
• Easy installation and alignment with the clipped design (1.265" width), speeding up assembly processes.
• Consistent performance from uniform thickness (0.084-0.097"), maintaining precise spacing and vibration resistance.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use.

Professional Applications & Engineering Value

This black-oxide steel clipped washer is engineered to address common industrial challenges such as corrosion, vibration-induced loosening, and assembly inefficiency. The black-oxide finish provides a protective layer that significantly reduces rust and oxidation in humid or corrosive settings, making it ideal for outdoor machinery, automotive assemblies, and heavy equipment. Its clipped design allows for quick placement and alignment, reducing installation time in high-volume production lines. With a Rockwell B40 hardness, it maintains structural integrity under repetitive loads and shocks, preventing deformation in demanding applications like construction frameworks or industrial fastening systems. By combining precise dimensions (e.g., 0.469" ID and 1.5" OD) with robust material properties, this washer ensures reliable performance, minimizes maintenance needs, and supports efficient, compliant operations in various sectors.
