Value Collection C676404 Oversized Key Stock 1/4 in Cold Drawn

Product Description

The VALUE COLLECTION C676404 is an oversized key stock bar used to transmit torque between a shaft and a mating hub, gear, sprocket, or pulley. Manufactured from cold drawn steel with a plain finish, this piece measures 0.25 inches high, 0.25 inches wide, and 12 inches long. The oversized designation means it is dimensioned slightly above standard key stock tolerances, allowing machinists to fit and file to final dimension for a precise, custom fit. Machinists, millwrights, and maintenance mechanics keep key stock on hand as a fundamental shaft-to-hub fastening component in rotating equipment assemblies.

Oversized key stock like the C676404 is used in industrial and commercial maintenance applications where standard-tolerance key stock does not provide a tight enough fit. Typical installations include pump shafts, conveyor drive shafts, gearbox input and output shafts, and motor-to-load couplings. The 12-inch length allows the stock to be cut to the required key length using standard metalworking tools. This product is sold individually per piece, with a minimum order quantity of 5 pieces.

Key Features

• Oversized tolerances allow fitting and filing for a precise, custom shaft-to-hub fit
• Cold drawn steel construction provides consistent dimensional accuracy and good surface finish
• Plain finish suits both bare installation and field modification without coating interference
• 12-inch bar length can be cut to any required key length on-site
• Square 0.25 inch by 0.25 inch cross-section fits standard 1/4-inch keyway applications

Compatibility

Designed as an oversized replacement or custom-fit key stock for rotating equipment assemblies requiring a 1/4-inch square keyway, including shaft-to-hub connections on pumps, motors, gearboxes, and conveyors.

Installation Notes

Installation is performed by machinists or millwrights using standard metalworking tools including files, bench grinders, and hacksaws or cold saws to cut and fit the key. De-energize and lock out all power to the equipment before disassembling any shaft or hub connection per applicable LOTO procedures. Do not drive the key into the keyway with excessive force; fit should be snug without distorting the shaft or hub bore. Follow applicable machinery safety standards and equipment manufacturer guidelines for keyway clearances and tolerances.
