Value Collection KP25952 Undersized Key Stock 1/4x1/4x36 in

Product Description

The VALUE COLLECTION KP25952 is an undersized key stock bar used to secure rotating components — such as gears, pulleys, and sprockets — to shafts in mechanical power transmission assemblies. Measuring 0.25 inches high by 0.25 inches wide by 36 inches long, this bar stock is manufactured from cold drawn steel and finished with a zinc plating for corrosion resistance. The undersized profile provides the close-tolerance fit needed in standard keyway applications. Machinists, millwrights, and maintenance technicians cut this stock to length on the job to suit specific shaft and hub configurations.

This key stock is suited for use in light to medium-duty power transmission applications found in industrial machinery, HVAC equipment, pumps, and conveyor systems. It is commonly installed during shaft-to-hub assemblies in both new construction and maintenance or repair work. The 36-inch bar length allows multiple cuts from a single piece, making it practical for shop stock and field repair kits alike.

Key Features

• Undersized profile for standard keyway fitment in shaft and hub assemblies
• Cold drawn steel construction for consistent dimensional tolerance and surface finish
• Zinc-plated finish provides basic corrosion resistance in typical shop and mechanical room environments
• 36-inch length can be cut to required dimensions on site
• Square cross-section at 0.25 inches x 0.25 inches suits common 1/4-inch keyway slots

Compatibility

Designed as a standard undersized key stock replacement for 1/4-inch keyway applications in industrial and mechanical power transmission equipment. Verify shaft and hub keyway dimensions before installation.

Installation Notes

Installation is typically performed by a machinist or millwright. De-energize all drive equipment and lock out and tag out power sources before removing or installing any shaft components. Cut key stock to the required length using a metal saw or mill; deburr all cut edges before fitting. Do not force or drive key stock into a keyway with excessive impact, as this can damage the shaft or hub bore.
