Hi-Pro Woodruff Keys

Stanho Hi-Pro Woodruff keys are manufactured in a wide range of standard sizes. Carbon keys are normally made from cold drawn SAE-1035 steel and alloy keys normally are made from SAE 8630 steel and are heat treated to Rockwell "C" 40-50. We can also make stainless keys upon request.
These keys are designed to be inserted into a keyway of a rotating shaft and are designed to rock in the seat for adjustment to angular spines. These keys are most commonly used to secure gears to transmission shafts. The feet of the key are why they can be installed quickly and accurately, thus increasing production speed and efficiency. The feet provide restricted movement in the keyway.
