Value Collection 33969 Undersized Key Stock 3/4 X 12 in

Product Description

The VALUE COLLECTION 33969 is a cold drawn steel undersized key stock bar used to secure rotating components to shafts in mechanical power transmission assemblies. Measuring 3/4 inches high by 3/4 inches wide by 12 inches long, this piece features a plain finish and is manufactured from cold drawn steel for consistent dimensional tolerances and reliable shear strength. Undersized key stock is intentionally produced slightly below nominal dimensions to allow for proper fit in standard keyways with appropriate clearance. Machinists, millwrights, and maintenance technicians use this stock to fabricate or replace keys in drive systems.

This key stock is suited for use in industrial and commercial mechanical assemblies where a 3/4-inch square keyway is required. Typical applications include motor-to-shaft connections, gear drives, pulley mounts, and other rotating equipment found in manufacturing, processing, and HVAC mechanical rooms. The 12-inch length allows the technician to cut the piece to the required key length on site, reducing waste and accommodating a range of shaft configurations.

Key Features

• Cold drawn steel construction provides consistent dimensional accuracy and good surface finish
• Undersized profile allows proper clearance fit in standard 3/4-inch square keyways
• 12-inch length can be cut to size in the field to suit various shaft and hub configurations
• Plain finish is suitable for most indoor mechanical applications and accepts coatings if needed
• Square cross-section at 3/4 inches high by 3/4 inches wide for straightforward torque transmission

Compatibility

Designed as a general-purpose undersized key stock for use in standard 3/4-inch square keyway applications across a wide range of mechanical power transmission equipment.

Installation Notes

Installation is typically performed by a machinist or millwright. De-energize and lock out all rotating equipment before removing or installing any key stock. The stock should be cut to length using appropriate metal-cutting tools and deburred before installation. Verify keyway dimensions and clearance fit before final assembly to ensure proper torque transfer without excessive play.
