Value Collection C676410 Oversized Key Stock 5/8x12 in

Product Description

The VALUE COLLECTION C676410 is an oversized key stock bar used to secure rotating components — such as pulleys, sprockets, and gears — to shafts in mechanical power transmission assemblies. Measuring 5/8 inches high by 5/8 inches wide by 12 inches long, this square-profile bar is manufactured from cold drawn steel, which provides consistent dimensional accuracy and a smooth surface finish straight from the mill. The plain finish is suitable for general industrial and mechanical service where additional corrosion protection is not required. Machinists, millwrights, and maintenance technicians cut this stock to the required key length for the application at hand.

Oversized key stock is specified when standard keyway fits require additional material for custom machining or when worn keyways need to be recut to a larger dimension. This bar stock is appropriate for use in light to moderate duty shaft-and-hub assemblies found in industrial machinery, HVAC drive systems, pump assemblies, conveyor drives, and similar rotating equipment. It is sold individually but subject to a minimum order quantity of 5 pieces per transaction.

Key Features

• Oversized profile at 5/8 inches high by 5/8 inches wide for applications requiring above-standard keyway dimensions
• 12 inches length allows the technician to cut multiple keys from a single bar
• Cold drawn steel construction delivers tight dimensional tolerances and a consistent surface finish
• Plain finish provides a clean surface ready for fitting, filing, or further machining
• Square cross-section suits a wide range of standard and custom keyway geometries

Compatibility

Designed as a general-purpose oversized key stock bar for shaft-and-hub assemblies requiring a 5/8-inch square key profile. Confirm keyway dimensions on both shaft and hub before cutting and fitting.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians. Always de-energize and lock out the drive system before removing or fitting shaft keys. Cut the key stock to length using appropriate metalworking tools and deburr all cut edges before fitting to avoid keyway damage. Ensure the finished key fits snugly in the keyway without excessive play before reassembling the hub or coupling.
