Value Collection KP1917 Undersized Key Stock 18-8 Ss

Product Description

The VALUE COLLECTION KP1917 is an undersized key stock bar used to transmit torque between a shaft and a mating hub or sprocket in mechanical drive assemblies. Machined from 18-8 stainless steel, this piece measures 3/4 inches high by 3/4 inches wide by 12 inches long. The undersized tolerance means the bar fits standard keyways with the slight clearance needed for easy assembly and disassembly. Machinists, millwrights, and maintenance technicians use undersized key stock when a press or interference fit is not required and when the key must slide or be removed during servicing.

This key stock is suited for general industrial maintenance and light fabrication work where corrosion resistance matters. The 18-8 stainless steel composition holds up in wet, washdown, or mildly corrosive environments better than plain steel equivalents. It can be cut to length with a metal-cutting bandsaw or hacksaw and finished to final dimension on a mill or surface grinder. Typical applications include conveyor drives, pump shafts, fan hubs, and similar rotating equipment found in industrial facilities, food-processing plants, and marine settings.

Key Features

• Undersized tolerance for easy assembly and field fitting without interference
• 18-8 stainless steel construction resists rust and corrosion in wet or washdown environments
• 3/4 inches x 3/4 inches cross-section suits standard square-keyway shafts in that size range
• 12-inch length can be cut to any shorter dimension on site
• Single-piece package ready for immediate use or stock

Compatibility

Designed as a standard undersized key stock replacement for rotating machinery applications requiring a 3/4-inch square keyway profile in corrosion-resistant stainless steel.

Installation Notes

De-energize and lock out all power to the drive before removing or installing key stock. Confirm the keyway dimensions on both the shaft and hub match the 3/4-inch square profile before cutting the bar to length. Use appropriate metalworking equipment when cutting or dressing the key, and deburr all edges to prevent galling during assembly. Follow applicable ANSI and OSHA lockout-tagout procedures throughout the service procedure.
