Mak-a-key 7007500750-12 Undersized Key Stock 12 in

Product Description

The MAK-A-KEY 7007500750-12 is an undersized key stock shaft in 18-8 stainless steel, cut to 12 inches in length. Key stock is used to secure rotating components - such as gears, pulleys, and sprockets - to shafts in mechanical and power-transmission assemblies. The undersized designation means the cross-section is manufactured to a tolerance below nominal, allowing a controlled fit in standard keyways without requiring additional machining. This piece ships as a single unit and is handled by millwrights, maintenance technicians, and mechanical contractors working on equipment drives and pump assemblies.

This key stock is suited for light industrial, HVAC equipment, and pump or fan drive applications where a corrosion-resistant material is required. The 18-8 stainless steel composition provides good resistance to rust and mild chemical exposure, making it a practical choice for wet environments, outdoor mechanical assemblies, and pump drives. It is sold individually and can be cut to a shorter length on-site using standard metalworking tools.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet or chemically exposed environments
• Undersized tolerance allows controlled fit in standard keyways without additional machining
• 12-inch length can be cut to size on-site with standard metalworking tools
• Single-piece packaging - order exactly the quantity needed
• UNSPSC Code 31163208 for procurement system compatibility

Compatibility

Designed as a standard-profile undersized key stock for use in mechanical shaft-and-hub assemblies requiring a 12-inch stainless steel key. Verify keyway dimensions and cross-section specifications against shaft and hub tolerances before installation.

Installation Notes

Shut down and lock out all powered equipment before removing or installing key stock. Confirm the keyway profile and cross-section tolerance match this undersized stock before cutting to final length. A machinist file or mill may be needed to deburr cut ends. Follow applicable machinery safety standards and facility lockout/tagout procedures throughout the service procedure.
