    Rounded Key
    Image of Attribute. Front orientation. Rounded Key. Undersized Machine Key Assortments.

    Rounded keys fill oval keyways completely, reducing stress on the key and shaft. In closed keyways, these keys won’t slide along the shaft. Their rounded ends also make it easy to slide gears, hubs, and other components into place.

    Cut keys to custom lengths. This key stock is undersized, so keys will fit slightly more loosely than standard keys and are best for inconsistent keyways. Use undersized keys when parts need to be taken apart frequently, such as for maintenance or prototyping. Either zinc- or zinc yellow-chromate plated, this key stock resists corrosion in wet environments.
