Each key measures 1\/2 inch long by 1\/8 inch wide and is manufactured from steel for reliable torque transmission. Sold in a pack of 50, this key conforms to USA Standard No. 404 dimensions, making it a direct match for standardized keyway slots found in drive shafts, pulleys, gears, and similar power-transmission components. Machinists, millwrights, and maintenance technicians typically keep these on hand for repair and assembly work across a broad range of industrial and mechanical equipment.\u003c\/p\u003e\u003cp\u003eThe 31950 Woodruff key is used in rotating shaft applications where a semicircular or standard key is required to prevent relative rotation between a shaft and a mounted component such as a pulley, sprocket, or gear hub. Typical install scenarios include pump shafts, motor shafts, fan hubs, and light-duty power-transmission drives in both industrial and commercial maintenance settings. The pack quantity of 50 suits service shops and maintenance teams that replace keys frequently during equipment overhaul.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eConforms to USA Standard No. 404 Woodruff key dimensions\u003c\/li\u003e\n\u003cli\u003eSteel construction for strength and wear resistance in torque-transmission applications\u003c\/li\u003e\n\u003cli\u003e1\/2 inch length x 1\/8 inch width fits standard No. 404 keyway slots\u003c\/li\u003e\n\u003cli\u003ePack of 50 units reduces per-unit cost for shops with recurring replacement needs\u003c\/li\u003e\n\u003cli\u003eCompact, consistent dimensions suited for precision shaft-hub fits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement for any shaft-hub assembly specifying a No. 404 Woodruff key with a 1\/2 inch by 1\/8 inch cross-section per USA Standard keyway specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eWoodruff keys are typically installed by machinists or maintenance mechanics using a press, mallet, and properly sized keyway broach or file for fitting. Ensure the shaft and hub keyways are clean and free of burrs before seating the key. Confirm the key seats fully into the shaft slot without rocking before pressing the hub.
