Value Collection KP25955 Undersized Key Stock 1/2x1/2x36 in

Product Description

The VALUE COLLECTION KP25955 is an undersized key stock bar used to secure rotating components such as gears, pulleys, and sprockets to shafts in mechanical power transmission assemblies. Measuring 0.5 inches high by 0.5 inches wide by 36 inches long, this bar is manufactured from cold drawn steel and finished with a zinc plating for corrosion resistance. The undersized designation means the cross-section dimensions are intentionally held slightly below nominal, allowing a controlled fit in standard keyway slots. Machinists and millwrights cut this stock to length on the job to suit the specific application.

This key stock is suited for general industrial, agricultural, and mechanical maintenance applications where a standard 1/2-inch square keyway drive connection is required. It is commonly used in repair and fabrication shops, manufacturing facilities, and field maintenance environments. The 36-inch bar length allows multiple keys to be cut from a single piece, making it practical for production or repeated service work on similar equipment.

Key Features

• Undersized profile provides controlled clearance fit in standard 1/2-inch square keyway slots
• Cold drawn steel construction offers consistent dimensional tolerances and good surface finish
• Zinc plating provides a baseline level of corrosion protection during storage and service
• 36-inch bar length allows multiple cuts per piece, reducing material waste
• Square cross-section at 0.5 inches x 0.5 inches suits a wide range of standard shaft and hub keyways

Compatibility

Designed as a general-purpose undersized key stock for use in standard 1/2-inch square keyway applications across industrial and mechanical power transmission equipment.

Installation Notes

Installation is typically performed by machinists or millwrights using a hacksaw, cold saw, or angle grinder to cut the stock to the required length. De-energize and lockout all equipment before servicing any shaft or hub assembly. Deburr cut ends before fitting the key into the keyway slot to ensure proper seating and prevent damage to mating components. Follow applicable machinery safety standards and facility lockout/tagout procedures during installation.
