Value Collection C676405 Oversized Key Stock 5/16x12 in

Product Description

The VALUE COLLECTION C676405 is an oversized key stock bar used to transmit torque between a shaft and a mating hub or sprocket in mechanical drive assemblies. Measuring 5/16 inches high by 5/16 inches wide by 12 inches long, this square-profile stock is manufactured from cold drawn steel with a plain finish. It is intended to be cut to the required length at the job site or shop, making it a flexible fit for maintenance and repair work across a wide range of machinery. Machinists, millwrights, and industrial maintenance technicians are the typical end users.

Oversized key stock is used where standard key dimensions are insufficient due to wear in the keyway or where upgraded torque capacity is needed. Applications include conveyor drives, pump shafts, fan assemblies, and general industrial power transmission equipment. The 12-inch length provides material for multiple cuts depending on the specific keyed connection requirements of the assembly being serviced.

Key Features

• Square profile: 5/16 inches high by 5/16 inches wide for oversized keyway fitment
• 12-inch length allows job-site cutting to required dimensions
• Cold drawn steel construction provides consistent dimensional tolerance and surface hardness
• Plain finish suitable for direct installation or further surface treatment
• Oversized designation accommodates worn keyways where standard stock no longer fits properly

Compatibility

Designed as an oversized replacement key stock for mechanical drive assemblies requiring a 5/16-inch square key profile, including shaft-to-hub connections on pumps, fans, conveyors, and similar power transmission equipment.

Installation Notes

Installation is typically performed by a machinist or millwright. De-energize and lock out the machine fully before removing or installing any shaft keys. Cut the stock to length using an appropriate metal-cutting tool and deburr all edges before fitting. Verify that the key seats fully in both the shaft keyway and the hub keyway before reassembling and torquing fasteners per the equipment manufacturer specifications.
