Value Collection -33979-1 Oversized Key Stock 7/16x7/16x12 in

Product Description

The VALUE COLLECTION -33979-1 is an oversized key stock bar used to secure rotating components to shafts in mechanical drive systems. Machined from cold drawn steel and finished with a zinc plating for corrosion resistance, this key stock measures 7/16 inches high, 7/16 inches wide, and 12 inches long. It is sized above standard dimensions to allow machinists and maintenance technicians to fit and file the key to an exact keyway, ensuring a tight, reliable fit. Machinists, millwrights, and industrial maintenance professionals typically source oversized key stock when standard sizing leaves excessive clearance.

This key stock is suited for use in mechanical power transmission assemblies including pumps, gearboxes, pulleys, sprockets, and fan hubs. The 12-inch length allows the piece to be cut down on-site to match the required keyway length. It is appropriate for both light and moderate duty applications where a keyed shaft connection is specified. The oversized cross-section provides extra material to work to final dimension when precision fitting is required.

Key Features

• Oversized 7/16 inches x 7/16 inches cross-section for custom fitting to keyways
• 12-inch length can be cut to required size on-site
• Cold drawn steel construction provides consistent hardness and dimensional accuracy
• Zinc plating adds corrosion resistance for general industrial environments
• Suitable for pumps, gearboxes, pulleys, sprockets, and similar shaft-mounted components

Compatibility

Designed as an oversized replacement or fitting blank for shaft keyway applications requiring a 7/16 inches x 7/16 inches key profile in mechanical power transmission equipment.

Installation Notes

Installation is typically performed by a machinist or qualified maintenance technician. Shut down and lock out all power to the drive system before removing or installing any shaft components. The key should be filed or ground to achieve a snug fit with no rocking in the keyway before final assembly. Follow applicable ANSI and facility safety standards for machine guarding and lockout/tagout procedures.
