Value Collection 33964 Undersized Key Stock 3/8x3/8x12 in

Product Description

The VALUE COLLECTION 33964 is an undersized key stock bar used to secure rotating components to shafts in mechanical drive assemblies. Machined from cold drawn steel with a plain finish, this key stock measures 3/8 inches high by 3/8 inches wide by 12 inches long. The undersized profile allows for precise fitment in standard keyways where slight clearance is required for assembly or light interference conditions. Machinists, maintenance technicians, and millwrights reach for key stock like this when building or restoring drive shafts, pulleys, gears, and sprocket assemblies across industrial and commercial equipment.

This key stock is suited for use in mechanical power transmission applications including pumps, fans, conveyors, and motor-to-shaft connections found in HVAC, industrial, and general maintenance settings. The 12-inch length allows a technician to cut the stock to the required finished length on-site using standard shop tools. Cold drawn steel construction provides consistent dimensional accuracy and adequate hardness for typical drive-shaft keyway loads in light-to-medium duty applications.

Key Features

• Undersized profile provides clearance fit in standard keyways for easier assembly
• Cold drawn steel construction delivers consistent cross-section dimensions and surface finish
• Plain finish with no coating — ready to cut, file, or fit to length in the field
• Square cross-section at 3/8 inches x 3/8 inches suits common shaft keyway sizes
• 12-inch bar length allows on-site cutting to required finished dimension

Compatibility

Designed as a standard undersized key stock replacement for use in 3/8-inch square keyways on pump shafts, motor shafts, and power transmission assemblies where cold drawn steel key material is specified.

Installation Notes

Key stock installation is typically performed by a machinist or qualified maintenance technician. De-energize and lock out all equipment before removing or installing shaft components. Cut key stock to finished length using a bandsaw, hacksaw, or abrasive cutoff tool, then deburr all edges before fitting into the keyway. Verify keyway and key dimensions with calipers before final assembly to confirm proper fit and avoid damage to shaft or mating bore.
