Value Collection 33968 Undersized Key Stock 5/8x12 in

Product Description

The VALUE COLLECTION 33968 is an undersized key stock bar used to secure rotating components such as gears, pulleys, and sprockets to shafts in mechanical drive systems. Manufactured from cold drawn steel with a plain finish, this key stock measures 5/8 inches high by 5/8 inches wide by 12 inches long. Cold drawing produces tight dimensional tolerances and improved surface finish, which is important in close-fit keyway applications. Machinists, maintenance technicians, and millwrights cut this bar stock to length and fit it to standard keyways during equipment assembly or repair.

This key stock is suited for use in general industrial, manufacturing, and mechanical maintenance applications where a standard undersized profile is required. The undersized designation means the cross-section is slightly below nominal dimensions, allowing easier insertion into keyways where standard stock would bind. Typical applications include motor-to-gearbox connections, conveyor drive assemblies, pump shafts, and fan hubs across light to medium industrial equipment.

Key Features

• Cold drawn steel construction provides improved dimensional accuracy and surface hardness compared to hot rolled alternatives
• Undersized profile allows controlled fit in standard keyways without binding
• 5/8 inches x 5/8 inches square cross-section suits common shaft and hub keyway configurations
• 12-inch length provides material for multiple cut-to-length pieces per bar
• Plain finish is ready for immediate installation or further machining

Compatibility

Designed as an OEM-style replacement or maintenance stock for mechanical drive assemblies requiring a 5/8 inches x 5/8 inches undersized square key profile in standard keyways.

Installation Notes

Key stock installation is typically performed by machinists or millwrights during shaft and hub assembly. Cut the bar to the required length using a bandsaw, cold saw, or angle grinder, and deburr all cut edges before fitting. Ensure the shaft and hub are fully de-energized and locked out before removing or installing any drive components. Verify keyway dimensions match the key stock profile before pressing or driving the key into position.
