Value Collection 33976 Oversized Key Stock 1/4 in Zinc-plated

Product Description

The VALUE COLLECTION 33976 is an oversized key stock bar used to transmit torque between a shaft and a mating hub or sprocket in mechanical drive assemblies. Machined from cold drawn steel and finished with a zinc plating for corrosion resistance, this key stock measures 0.25 inches high, 0.25 inches wide, and 12 inches long. The oversized designation means the cross-section is intentionally manufactured slightly above nominal dimension to allow machinists and maintenance techs to fit or file the key to exact tolerance. Sold individually, with a minimum order quantity of 5 pieces per transaction.

This key stock is suited for light-to-medium duty power transmission applications including electric motor shafts, pump couplings, gear reducers, conveyor drive shafts, and fan hubs in both industrial and commercial mechanical systems. Maintenance mechanics, millwrights, and HVAC technicians commonly use oversized key stock when rebuilding drive assemblies where standard-size keys have worn keyways or when a custom-fit key is needed. The 12-inch length allows the bar to be cut down to the required finished length on site.

Key Features

• Oversized cross-section for custom fitting to worn or non-standard keyways
• Cold drawn steel construction provides consistent dimensional accuracy and good machinability
• Zinc plating offers baseline corrosion protection in moderate environments
• 12-inch bar length can be cut to finished length in the field
• Square 0.25 inch by 0.25 inch profile suits common small-shaft drive applications

Compatibility

Designed as an OEM-style replacement or maintenance-grade oversized key stock for light-to-medium duty mechanical drive assemblies requiring a 1/4-inch square key profile.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician familiar with shaft and keyway tolerances. De-energize and lock out the drive unit before removing any shaft components. Use a file or surface grinder to bring the oversized key to the precise fit required by the keyway; never force an unfit key into a shaft slot. Verify proper key engagement and hub seating before returning the assembly to service.
