Value Collection 33967 Undersized Key Stock 9/16 X 12 in

Product Description

The VALUE COLLECTION 33967 is an undersized key stock bar used to secure rotating components such as gears, pulleys, and sprockets to shafts in mechanical and power-transmission assemblies. Cut from cold drawn steel, this key stock measures 9/16 inches high by 9/16 inches wide by 12 inches long and carries a plain finish ready for field fitting. Undersized tolerance allows the bar to fit snugly into standard keyways without binding, making it a common choice for maintenance and repair tasks across industrial and commercial mechanical systems. Machinists, millwrights, and maintenance technicians typically install this type of hardware.

This key stock suits a wide range of shaft-and-hub assemblies found in HVAC equipment drives, pump drive trains, conveyor systems, and general industrial machinery. The 9/16 inches square cross-section accommodates standard keyway dimensions for mid-range shaft diameters. The 12-inch length allows the installer to cut the bar to the required finished length on-site using a bandsaw, angle grinder, or hacksaw. It is sold individually per piece with a minimum order quantity of 2 pieces.

Installation Notes

Installation is typically performed by a machinist or qualified maintenance technician. Always de-energize and lock out the drive system before removing or installing key stock. The key stock should be cut to the required length using appropriate metal-cutting tools and deburred before fitting. Verify keyway dimensions in both shaft and hub before installation to confirm proper fit and engagement.
