Mak-a-key 7005000500-12 Undersized Key Stock 12 in

Product Description

The MAK-A-KEY 7005000500-12 is an undersized key stock cut to 12 inches in length, made from 18-8 stainless steel. Key stock is used to secure rotating components such as pulleys, gears, and sprockets to shafts, transmitting torque while preventing relative motion between the mating parts. The undersized designation indicates the stock is machined slightly below nominal width, which allows it to seat cleanly into standard keyways without binding. Stainless steel construction provides corrosion resistance in wet, chemical, or outdoor service environments. This piece weighs 3.4 pounds and ships as a single unit.

Undersized key stock is a standard fastening component found across HVAC drive systems, pump assemblies, conveyor equipment, and general mechanical power transmission applications. It is used wherever a shaft-to-hub connection requires a removable, torque-transmitting key. HVAC technicians, millwrights, and mechanical contractors encounter this material when servicing belt-drive air handlers, fans, blowers, and pump drives. The 12-inch length allows the installer to cut the stock to the required finished key length in the field using standard metalworking tools.

Key Features

• Undersized key stock type seats cleanly into standard keyways without binding
• 18-8 stainless steel construction resists corrosion in wet and chemical environments
• 12-inch length provides flexibility for field cutting to finished key dimensions
• Single-piece package suits maintenance and repair quantity needs
• UNSPSC Code 31163208 for procurement and catalog classification

Compatibility

Designed as a standard undersized key stock for use in shaft-to-hub connections across general mechanical power transmission and HVAC drive system applications where a nominal stainless steel key is required.

Installation Notes

Installation is typically performed by licensed HVAC technicians, millwrights, or mechanical contractors. Disconnect and lock out all electrical power and relieve any stored mechanical energy before removing or installing key stock. Cut the stock to finished length using appropriate metalworking tools and deburr all cut edges before seating. Verify keyway dimensions on both shaft and hub before installation to ensure proper fit.
