• Superior fatigue resistance for extended service life in high-vibration applications
• Optimized for inch-system assemblies in North American manufacturing and maintenance operations

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these 17-4 PH stainless steel flat washers provide critical corrosion resistance in chemical processing, marine environments, and outdoor installations. The precise inner diameter of 0.313" ensures perfect alignment with 1/4" screw sizes, eliminating play while the 0.75" outer diameter distributes clamping force effectively across softer materials. With Rockwell C40 hardness, these flat washers maintain dimensional stability under heavy loads, preventing embedding and surface damage in structural assemblies, machinery mounts, and precision equipment where vibration resistance and long-term reliability are paramount.
