Mak-a-key C207-362214305 Oversized Key Stock 12in Steel

Product Description

The MAK-A-KEY C207-362214305 is an oversized key stock used to secure rotating components such as gears, pulleys, and sprockets to shafts in mechanical power transmission assemblies. Manufactured from C1045 steel with a zinc-plated finish, this key stock provides solid shear strength and corrosion resistance in demanding shop and field environments. Each piece measures 12 inches in length, with a height of approximately 0.866 inches and a width of approximately 0.551 inches, sized to fit oversized keyway slots. This package includes 3 pieces and weighs 1.641 pounds total. Machinists, millwrights, and industrial mechanics are the primary installers of this component.

This oversized key stock is suited for use in industrial and commercial power transmission applications where standard key stock dimensions are insufficient. Typical install scenarios include heavy-duty shaft-to-hub connections in conveyor systems, pump assemblies, fan drives, and gearboxes. The zinc plating provides a measure of protection against corrosion during storage and in environments with occasional moisture exposure. The C1045 steel material specification indicates medium-carbon steel, appropriate for moderate-to-high torque keyway applications. This package quantity of 3 pieces supports both single-repair jobs and light-volume production work with a minimum order quantity of 1.

Key Features

• Oversized key stock profile for keyways requiring dimensions beyond standard sizing
• C1045 medium-carbon steel construction for solid shear strength in torque-transmitting applications
• Zinc-plated finish provides corrosion resistance during storage and service
• 12-inch length allows cutting to custom fit for a wide range of shaft lengths
• Package includes 3 pieces, supporting both single-repair and small-batch use

Compatibility

Designed as an OEM-style replacement or aftermarket option for oversized keyway shaft assemblies in industrial power transmission equipment. Verify keyway slot dimensions against the 22.00 mm height and 14.00 mm width profile before installation.

Installation Notes

Installation is typically performed by millwrights or industrial mechanics. De-energize and lock out all power to rotating equipment before servicing any shaft or hub assembly, following OSHA lockout/tagout procedures. Key stock should be cut to the required length using appropriate metalworking tools and deburred before fitting into the keyway. Do not force-fit key stock that does not match keyway slot dimensions, as improper fit can cause premature component failure.
