Value Collection KP1915 Undersized Key Stock 18-8 Ss

Product Description

The VALUE COLLECTION KP1915 is an undersized key stock bar used to transmit torque between a shaft and a hub in mechanical drive assemblies. Machined to undersized tolerances, this key stock allows for easier fitting and adjustment during installation compared to standard-tolerance stock. The bar measures 1/2 inch high by 1/2 inch wide by 12 inches long and is made from 18-8 stainless steel, providing corrosion resistance in wet, washdown, or chemically exposed environments. Machinists, millwrights, and maintenance technicians commonly use this type of key stock when fitting pulleys, sprockets, gears, and couplings to rotating shafts.

This key stock is suited for use in both light industrial and commercial mechanical applications where a standard square key profile is required. The 1/2 inch square cross-section fits keyways in shafts and hubs requiring that profile. The 12-inch length allows the stock to be cut to the required finished key length on-site using standard metalworking tools. The 18-8 stainless steel material makes it appropriate for food processing equipment, marine hardware, pump assemblies, and other environments where carbon steel would corrode.

Key Features

• Undersized tolerance for easier keyway fitting and reduced hand-fitting time
• 18-8 stainless steel construction resists corrosion in wet and washdown environments
• 1/2 inch x 1/2 inch square cross-section for standard square keyway applications
• 12-inch length can be cut to finished key length in the field
• Single-piece quantity suitable for maintenance, repair, and small-batch use

Compatibility

Designed as a standard square undersized key stock for use in shaft-to-hub assemblies requiring a 1/2 inch square keyway profile across industrial, commercial, and mechanical maintenance applications.

Installation Notes

Installation is typically performed by a millwright or maintenance machinist. Power down and lock out all rotating equipment before removing or installing key stock. The stock should be cut to the required length and deburred before fitting into the keyway. Avoid striking the key into position with excessive force, as this can distort the keyway or damage the hub bore.
