Value Collection KP1916 Undersized Key Stock 18-8 Ss

Product Description

The VALUE COLLECTION KP1916 is an undersized key stock bar used to secure rotating components such as gears, pulleys, and sprockets to shafts in mechanical drive assemblies. Measuring 5/8 inches high by 5/8 inches wide by 12 inches long, this bar is manufactured from 18-8 stainless steel for corrosion resistance in wet or chemically exposed environments. Undersized tolerancing allows the key to fit keyways where clearance is required for easier assembly and disassembly. Machinists, millwrights, and maintenance technicians cut this stock to length to suit individual applications.

This key stock is suited for light-to-medium duty shaft-to-hub connections in industrial, commercial, and marine settings where corrosion resistance is a priority. Typical applications include pump drives, conveyor systems, fan assemblies, and HVAC equipment drive trains. The 18-8 stainless alloy performs well in humid, washdown, and mildly corrosive environments where plain steel key stock would degrade over time.

Key Features

• Undersized tolerance for easier keyway fitment and cleaner assembly
• 18-8 stainless steel construction provides corrosion and oxidation resistance
• 5/8 inches x 5/8 inches square cross-section for high-torque shaft connections
• 12-inch bar length can be cut to any required key length with standard shop tools
• Single-piece stock with no welds or joints along the length

Compatibility

Designed as a standard undersized key stock bar suitable for 5/8-inch square keyways in shaft-and-hub assemblies across industrial, commercial, and mechanical maintenance applications.

Installation Notes

Key stock installation is typically performed by machinists or millwrights using a band saw, hacksaw, or cold saw to cut the bar to the required length, followed by filing or grinding to achieve final fit. Deburr all cut ends before installation to prevent keyway damage and ensure proper seating. Disconnect and lock out all power to the drive assembly before removing or installing any shaft keys. Consult equipment manufacturer tolerances and applicable machinery safety standards before placing the key in service.
