S-91717A115 0.344" ID x 1.125" OD Clipped Washers

Key Features & Benefits at a Glance

• Enhanced load distribution with 1.125" OD and 0.344" ID for superior surface coverage and reduced pressure on 5/16" fasteners
• Exceptional durability from steel construction with Rockwell B40 hardness, resisting deformation under stress
• Secure anti-rotation performance due to the 0.952" clipped width, preventing washer spin during assembly
• Consistent thickness tolerance (0.056-0.071") ensures uniform clamping force and reliable joint integrity
• Full regulatory compliance with RoHS 3 and REACH standards, meeting global environmental and safety requirements
• Optimized for industrial environments with inch system compatibility, simplifying procurement and replacement

Professional Applications & Engineering Value

Engineered for demanding industrial applications, this clipped washer solves critical assembly challenges by providing stable bearing surfaces and preventing rotational movement. The steel material and Rockwell B40 hardness ensure long-term reliability in high-vibration environments, such as machinery, automotive subassemblies, and structural frameworks. Its precise 0.344" ID and 1.125" OD dimensions guarantee perfect fitment for 5/16" screws, reducing installation errors and maintenance downtime. The unique clipped design allows for closer placement to edges and other components, offering flexibility in confined spaces while maintaining superior performance under heavy loads.
