Value Collection 40164 Oversized Key Stock Steel

Product Description

The VALUE COLLECTION 40164 is an oversized key stock made from steel with an unfinished surface finish. Key stock is a precision bar used in mechanical power transmission to secure rotating components — such as gears, pulleys, and sprockets — to shafts, preventing relative rotation under load. This piece measures 6.00 millimeters in height and 6.00 millimeters in width, placing it in the oversized category for standard keyway applications. Machinists, millwrights, and industrial maintenance technicians install key stock during shaft-to-hub assemblies. The unfinished steel construction allows for field cutting, filing, and fitting to exact keyway tolerances on the job.

This key stock is suited for general industrial and mechanical maintenance applications where an oversized key fit is required. Typical use cases include retrofitting worn keyways, building up clearance on existing shaft assemblies, or serving as raw stock that is machined down to a precise fit. It is appropriate for both light and moderate power transmission assemblies in manufacturing, maintenance, and repair environments. Sold individually, it gives technicians the flexibility to cut and fit to the specific shaft and hub dimensions at hand.

Key Features

• Steel construction provides strength and machinability for keyway fitting applications
• Unfinished surface allows for field cutting, grinding, and fitting to exact tolerances
• Oversized designation accommodates worn or enlarged keyways requiring a tighter fit
• 6.00 mm height and 6.00 mm width cross-section for standard square-key configurations
• Sold as a single piece to allow flexible quantity purchasing for maintenance and repair work

Compatibility

Designed as a general-purpose oversized key stock for use in standard square-keyway shaft-and-hub assemblies across industrial and mechanical maintenance applications.

Installation Notes

Key stock installation is typically performed by machinists or millwrights. Always de-energize and lock out the machine before servicing any shaft assembly. Key stock may require cutting to length and filing or grinding to achieve a proper slip fit within the keyway — avoid hammering a key stock piece into a keyway that is undersized, as this can damage the hub or shaft. Follow applicable machinery safety standards and equipment manufacturer specifications when sizing and fitting key stock.
