Value Collection KP25956 Undersized Key Stock 5/8 in Square 36 in

Product Description

The VALUE COLLECTION KP25956 is an undersized key stock bar used to transmit torque between a shaft and a hub, pulley, gear, or sprocket in mechanical power transmission assemblies. Measuring 5/8 inch wide by 5/8 inch high and 36 inches long, this square-profile key stock is cold drawn for close dimensional tolerances and consistent surface finish. A zinc-plated coating provides a baseline layer of corrosion resistance for storage and light-duty service environments. Machinists, millwrights, and maintenance technicians use key stock like this to fabricate custom-length keys by cutting to the required dimension on the job.

This key stock is suited for industrial and commercial maintenance applications where square-profile keys are required in shaft keyways. It is appropriate for use in motor-to-shaft couplings, conveyor drives, pump shafts, fan hubs, and similar rotating machinery found in HVAC mechanical rooms, industrial process equipment, and general plant maintenance settings. The 36-inch bar length allows multiple keys to be cut from a single piece, reducing waste and allowing size fitting at the bench.

Key Features

• Square profile at 5/8 inch wide by 5/8 inch high for standard square keyway applications
• 36-inch bar length allows multiple cuts per piece
• Cold drawn steel construction provides tight dimensional tolerances
• Undersized designation ensures proper clearance fit within standard keyways
• Zinc-plated finish offers basic corrosion resistance during storage and handling

Compatibility

Designed as an OEM-style replacement or fabrication-stock key bar for mechanical power transmission assemblies requiring a 5/8-inch square undersized key profile in standard shaft keyways.

Installation Notes

Installation is typically performed by a machinist or millwright. Shut down and lock out all equipment per LOTO procedures before servicing any shaft or keyway. Cut the key stock to the required length using a metal-cutting saw or mill, and deburr all cut edges before fitting. Never drive a key into a keyway with a hammer without confirming proper clearance, as a forced fit can damage the shaft or hub bore.
