Value Collection 33983 Oversized Key Stock 7/8 X 12 in

Product Description

The VALUE COLLECTION 33983 is an oversized key stock bar used to secure rotating components — such as gears, pulleys, and sprockets — to shafts in mechanical power transmission assemblies. Machined from cold drawn steel and finished with a zinc plating for corrosion resistance, this key stock measures 7/8 inches high by 7/8 inches wide by 12 inches long. Machinists, millwrights, and maintenance technicians use key stock to fill keyways and prevent relative rotation between mating parts under load. The cold drawn process improves surface finish and dimensional consistency compared to hot rolled alternatives, making it well-suited for close-tolerance keyway fits.

This oversized key stock is appropriate for industrial maintenance, repair, and fabrication applications where a standard key stock dimension does not provide sufficient material for fitting or custom machining. It is commonly cut to length on-site using a bandsaw or mill and fitted to keyways in motors, pumps, conveyors, and rotating shaft assemblies across light to medium industrial settings. The zinc plating provides a measure of protection during storage and in mildly corrosive environments.

Key Features

• Cold drawn steel construction for consistent dimensional tolerances and improved surface finish
• Zinc-plated finish for corrosion resistance during storage and service
• Oversized profile at 7/8 inches high by 7/8 inches wide provides material for custom fitting and machining
• 12-inch length allows on-site cutting to the required key length
• UNSPSC Code 31163208 for procurement and catalog classification

Compatibility

Designed as an oversized key stock replacement or fabrication blank for shaft and hub keyway applications in rotating mechanical assemblies. Verify keyway dimensions before installation, as oversized stock requires machining to final fit.

Installation Notes

Installation is typically performed by a machinist or millwright. De-energize all connected machinery and lock out or tag out power sources before working on any shaft or drive assembly. Key stock is commonly cut to length and dressed with a file or mill to achieve a snug, non-interference fit within the keyway. Never drive key stock with excessive force, as distortion can prevent proper seating and may damage the hub or shaft keyway.
