Mak-a-key 7006250625-12 Undersized Key Stock 12 in Ss

Product Description

The MAK-A-KEY 7006250625-12 is an undersized key stock measuring 12 inches in length, constructed from 18-8 stainless steel. Key stock is a precision-cut bar used to secure rotating components such as gears, pulleys, and sprockets to shafts, transmitting torque and preventing relative rotation. The undersized designation means the stock is manufactured to a tolerance below nominal dimensions, allowing for easier fitting into standard keyways without the need for custom machining. This piece is suited for maintenance, repair, and fabrication work across mechanical, HVAC, and industrial applications where corrosion resistance is a priority.

This 12-inch stainless steel key stock is appropriate for residential and light commercial equipment repair as well as general industrial fabrication tasks. It is commonly used by millwrights, HVAC technicians, and maintenance mechanics working on pump assemblies, fan shafts, blower assemblies, and conveyor drives where a corrosion-resistant drive connection is needed. The single-piece format allows technicians to cut the stock to the required length on site using standard metal-cutting tools.

Key Features

• Undersized tolerance allows installation into standard keyways without additional fitting or custom machining
• 18-8 stainless steel construction provides corrosion resistance in wet or humid environments
• 12-inch length can be field-cut to match specific shaft and keyway requirements
• Single-piece packaging suitable for individual repair or low-volume fabrication jobs
• UNSPSC Code 31163208 for procurement and inventory classification

Compatibility

Designed as a standard-profile undersized key stock suitable for use in keyways on shafts where an undersized fit is specified; confirm keyway dimensions and nominal key size before installation.

Installation Notes

Installation of key stock is typically performed by a qualified millwright or mechanical technician. De-energize and lock out all power to the driven equipment before removing or installing any drive components. Use appropriate metal-cutting tools to trim the key stock to the required length, and deburr all cut edges before assembly to ensure proper seating and prevent damage to mating components.
