Mak-a-key C207-360808305 Oversized Key Stock 12in Steel

Product Description

The MAK-A-KEY C207-360808305 is an oversized steel key stock used to transmit torque between a shaft and a mating component such as a gear, pulley, or sprocket. Manufactured from C1045 steel with a zinc-plated finish, this key stock measures 12 inches in length with an 8 mm height and 8 mm width. Each package contains 5 pieces. Machinists, millwrights, and maintenance technicians use key stock when fitting or replacing drive components in mechanical assemblies where positive shaft locking is required.

This key stock is suited for light industrial, commercial, and mechanical maintenance applications where an oversized profile is needed for a secure shaft-to-hub fit. It is commonly used in pump drives, conveyor systems, fan assemblies, and HVAC equipment mechanical drives. The zinc-plated finish provides a basic level of corrosion resistance for indoor and sheltered installations. Sold in a 5-piece package, making it practical for service shops and field technicians who replace key stock regularly.

Installation Notes

Installation is typically performed by a millwright or qualified maintenance technician. De-energize and lock out all power to the drive assembly before removing or installing key stock. Key stock length may be cut to fit using a metal-cutting saw or grinder. Ensure keyway and key stock surfaces are clean and free of burrs before assembly to achieve proper fit and torque transmission.
