Steelworks square key stock is a precision-machined steel bar used to lock a pulley, gear, sprocket, or hub onto a shaft so it transmits torque without slipping. Each 12" length cuts down to the exact key length your application needs, and the square profile drops directly into standard ASME B17.1 keyways.

• 1/4" square key stock, 12" long
• Machined to ASME B17.1 standard dimensions for a clean keyway fit
• Zinc-plated low-carbon steel resists surface rust before and after installation
• Standard pairing: shafts 15/16" to 1-1/4"
• General motors, sprockets, pulleys, and v-belt drives on common 1" and 1-1/8" shafts
• Cuts to length with a hacksaw, bandsaw, or abrasive cut-off wheel

Tip: A 1/4" square key is the workhorse size; keep a few cut lengths in your maintenance kit for replacement on most motors and gearboxes.
