Value Collection C676409 Oversized Key Stock 9/16 X 12 in

Product Description

The VALUE COLLECTION C676409 is an oversized key stock bar used to transmit torque between a shaft and a mating hub or sprocket in mechanical drive assemblies. Machined from cold drawn steel and left with a plain finish, this key stock measures 9/16 inches high by 9/16 inches wide by 12 inches long. The square cross-section profile is sized intentionally larger than standard tolerances, allowing machinists and maintenance technicians to file or grind the piece to an exact slip or interference fit for their specific keyway. It ships in a package quantity of five pieces.

Oversized key stock is used wherever a standard-tolerance bar would leave too much slop in a worn or custom-broached keyway. Typical applications include industrial equipment repair, custom shaft-to-hub assemblies, conveyor drives, pump shafts, and gearbox retrofits. Millwrights, maintenance machinists, and industrial mechanics install this type of stock across light and heavy manufacturing environments. The 12-inch bar length provides enough material to cut multiple shorter keys from a single piece, reducing scrap and setup time on the bench.

Key Features

• Oversized cross-section (9/16 inches x 9/16 inches) allows custom fitting to worn or non-standard keyways
• Cold drawn steel construction provides consistent grain structure and good surface finish for machining
• 12-inch bar length yields multiple usable key blanks per piece
• Plain finish — no coating or plating to interfere with dimensional fitting or subsequent machining
• Sold in a package of five bars for bench-stock convenience

Compatibility

Designed as an oversized replacement or custom-fit key stock for square keyway applications in shaft-and-hub assemblies where standard-tolerance bar stock does not provide adequate fit; verify keyway dimensions and required tolerances before installation.

Installation Notes

Installation is typically performed by a qualified machinist or millwright. De-energize and lock out all equipment before removing or installing shaft keys. The oversized stock requires bench filing, grinding, or milling to achieve the target fit class for the specific keyway; do not force an unfitted bar into a keyway under any circumstances. Follow applicable machinery safety standards and facility lockout/tagout procedures throughout the service process.
