Hi-Profile Machine Keys

Hi-Pro keys, or high profile keys, are a variation of woodruff keys with the added feature of “feet.” These feet keep the key from rocking in the key way while still allowing it to adjust to angular spines. This design also allows the key to be installed quickly and accurately thus improving assembly efficiency. Hi-pro keys are commonly used to lock pulleys and gears to transmission shafts.
