Value Collection KP25958 Undersized Key Stock 7/8x7/8x36 in

Product Description

The VALUE COLLECTION KP25958 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 7/8 inches high by 7/8 inches wide by 36 inches long, this bar stock is manufactured from cold drawn steel and finished with a zinc plating for corrosion resistance. The undersized designation means the cross-section is machined slightly below nominal dimensions, allowing a slip fit into standard keyways without requiring additional hand-fitting. Machinists, millwrights, and maintenance technicians use this stock as raw material, cutting it to the required length for each application.

This key stock is suited for general industrial and mechanical maintenance applications where a square-profile key is needed. It is commonly used in rotating shaft assemblies across manufacturing, agricultural equipment, conveyor systems, and pump drives. The 36-inch bar length provides material for multiple cuts. The zinc-plated finish offers light corrosion protection suitable for indoor or sheltered environments. Technicians working on rotating machinery will cut this bar to length using a bandsaw, angle grinder, or hacksaw, then deburr cut ends before installation.

Key Features

• Undersized cross-section for slip fit into standard keyways without hand-filing
• Square profile: 7/8 inches high by 7/8 inches wide
• 36-inch bar length yields multiple cuts per piece
• Cold drawn steel construction for consistent dimensional accuracy and strength
• Zinc-plated finish provides light corrosion resistance for indoor applications

Compatibility

Designed as an OEM-style replacement or maintenance-stock key bar for standard 7/8-inch square keyways found in industrial shaft and hub assemblies.

Installation Notes

Installation is typically performed by machinists or millwrights. Isolate and lock out the shaft assembly before removing or installing key stock per OSHA lockout/tagout procedures. Cut bar stock to required key length and deburr all cut edges before fitting into the keyway. Do not force an oversized or un-deburred key into a keyway, as this can damage the shaft or hub bore.
