Value Collection KP1913 Undersized Key Stock 18-8 Ss

Product Description

The VALUE COLLECTION KP1913 is an undersized key stock bar used to secure rotating components — such as gears, pulleys, and sprockets — to shafts in mechanical power transmission assemblies. Machined from 18-8 stainless steel, this key stock measures 3/8 inches high by 3/8 inches wide by 12 inches long. The undersized designation means the cross-section is ground slightly below nominal, allowing controlled fit in standard keyways where closer tolerances or easier installation are required. Machinists, millwrights, and maintenance technicians working on pumps, conveyors, fans, and similar rotating equipment use key stock like this as a cut-to-length raw material for custom key fabrication.

This key stock is suited for light to medium-duty shaft-to-hub connections in both industrial and commercial mechanical systems. The 18-8 stainless steel construction makes it appropriate for environments where corrosion resistance matters, including food-processing equipment, marine-adjacent installations, and wet or washdown areas. The 12-inch bar length gives technicians flexibility to cut individual keys to the exact length required by the keyway and hub specification on the job.

Key Features

• Undersized cross-section for controlled fit in standard keyways
• 18-8 stainless steel construction provides corrosion resistance in wet or harsh environments
• 3/8 inches x 3/8 inches cross-section suits common square-key shaft configurations
• 12-inch length allows field cutting to required key length
• Single-piece stock — cut and finish to spec on the job or in the shop

Compatibility

Designed as a cut-to-length undersized key stock for use in standard 3/8-inch square keyways found in mechanical power transmission assemblies. No specific OEM model compatibility was provided in the product data.

Installation Notes

Installation is typically performed by a machinist or millwright. Always de-energize and lock out the drive system before removing or installing any shaft key. Cut the bar to the required length using a bandsaw, cold saw, or angle grinder, then deburr all edges before fitting. Verify keyway dimensions and key fit before final assembly to ensure proper torque transfer and prevent shaft or hub damage.
