Value Collection KP25959 Undersized Key Stock 1x1x36 in

Product Description

The Value Collection KP25959 is an undersized key stock bar used to secure rotating components — such as gears, pulleys, and sprockets — to shafts in mechanical drive assemblies. Measuring 1 inch wide by 1 inch high by 36 inches long, this bar stock is manufactured from cold drawn steel and finished with a zinc plating for corrosion resistance. Undersized tolerances allow the key to fit standard keyways with controlled clearance, making it suitable for applications where precise fit and reliable torque transmission are required. Machinists and millwrights typically cut this stock to length on-site to match the specific keyway depth of the assembly being serviced.

This key stock is used in industrial maintenance, mechanical repair, and original equipment manufacturing environments. It is appropriate for use in power transmission applications including pump shafts, conveyor drives, fan assemblies, and motor couplings. The 36-inch bar length provides enough material to yield multiple cut pieces from a single bar, reducing waste and cost per key in high-volume or multi-job scenarios. It is handled by machinists, maintenance mechanics, and industrial trades working on rotating equipment.

Key Features

• Undersized key stock type for controlled clearance fit in standard keyways
• Cold drawn steel construction for consistent dimensional accuracy and surface finish
• Zinc-plated finish provides a base level of corrosion protection
• 1 inch wide by 1 inch high cross-section suits heavy-duty shaft diameters
• 36-inch length allows multiple keys to be cut from a single bar

Compatibility

Designed as a standard undersized key stock replacement for use in industrial power transmission assemblies where a 1-inch square keyway cross-section is specified.

Installation Notes

Installation is typically performed by a machinist or maintenance mechanic using standard metal cutting and fitting tools. Shut down and lock out all rotating equipment before removing or installing any shaft keys. The bar should be cut to the required length and deburred before fitting. Verify keyway dimensions and tolerances against the shaft and hub specifications before final assembly.
