Mak-a-key 7010001000-12 Undersized Key Stock 18-8 Ss

Product Description

The MAK-A-KEY 7010001000-12 is an undersized key stock bar used to transmit torque between a shaft and a mating hub, gear, pulley, or sprocket. Measuring 1 inch wide by 1 inch high by 12 inches long, it is manufactured from 18-8 stainless steel for corrosion resistance in wet or chemically aggressive environments. The undersized tolerance allows the key to slide into standard keyways without binding, making fitting and replacement straightforward. Machinists, millwrights, and maintenance technicians use this key stock in power transmission assemblies across industrial, commercial, and mechanical service applications.

This key stock is suited for use in pump drives, conveyor systems, fan shafts, and similar rotating equipment where a standard square key profile is required. The 12-inch length allows the bar to be cut to a custom fit on-site using standard metalworking tools. Stainless steel construction makes it a practical choice for food processing, marine, and outdoor installations where carbon steel would corrode prematurely.

Compatibility

Designed as an OEM-style replacement or service key stock for rotating equipment assemblies that use a standard 1-inch square keyway profile in shaft and hub connections.

Installation Notes

Installation is typically performed by a millwright, machinist, or qualified maintenance technician. De-energize and lock out the drive equipment fully before removing or installing any key stock. Cut the bar to length using a bandsaw, hacksaw, or milling machine, and deburr all cut edges before fitting. Verify shaft and hub keyway dimensions against the key stock profile before final assembly to ensure proper fit and torque transfer.
