McMaster 98800A130 Zinc-Plated Steel Undersized Machine Key Assortment Rounded, with 25 Pieces 40LJ74 400 in-lb Voltage 20 VSince they fit more loosely than standard keys, these undersized keys are best for uneven keyways or when you need to disassemble parts frequently, such as during maintenance or prototyping. Made of steel, all keys offer good strength. Rounded keys fill oval keyways completely, reducing stress on the key and shaft. In closed keyways, these keys wont slide along the shaft. Their rounded ends also make it easy to slide gears, hubs, and other components
