Value Collection 33971 Undersized Key Stock Cold Drawn Steel

Product Description

The VALUE COLLECTION 33971 is an undersized key stock bar used to secure rotating components such as gears, pulleys, and sprockets to shafts in mechanical drive systems. Measuring 1 inch high by 1 inch wide by 12 inches long, it is manufactured from cold drawn steel with a plain finish. Cold drawn steel provides tight dimensional tolerances and consistent surface hardness, making this key stock well suited for precision power transmission applications. Machinists, millwrights, and maintenance technicians cut and fit this stock to length during shaft and hub assembly work.

This key stock is appropriate for use in industrial machinery, conveyor systems, pump assemblies, and general mechanical drive applications where a standard undersized key fit is required. The 12-inch bar length allows the installer to cut multiple keys from a single piece, reducing material waste. It is suited for both light and moderate duty shaft-to-hub connections in manufacturing and maintenance environments.

Key Features

• Undersized key stock type for standard undersized keyway fits
• Cold drawn steel construction for consistent dimensional tolerances and surface hardness
• 1 inch high by 1 inch wide cross section
• 12-inch bar length allows on-site cut-to-length use
• Plain finish with no coating, ready for immediate installation or further machining

Compatibility

Designed as an OEM-style replacement or new-installation key stock for mechanical drive applications requiring a 1 inch by 1 inch undersized keyway cross section in cold drawn steel.

Installation Notes

Installation is typically performed by a machinist or millwright. Ensure the shaft and hub are fully de-energized and locked out before removing or installing key stock. Use a file, grinder, or saw to cut the key to the required length, and deburr all edges before fitting. Verify keyway dimensions match the key stock cross section before assembly to prevent shaft or hub damage.
