Value Collection MP31954 606 Woodruff Key Steel 10-pack

Product Description

The VALUE COLLECTION MP31954 is a 606 Standard Woodruff key used to secure rotating components — such as pulleys, gears, and sprockets — to shafts in mechanical assemblies. Measuring 3/4 inch long by 3/16 inch wide, this key fits into a milled semicircular keyway and prevents relative rotation between the shaft and the mounted component. Constructed from steel for strength and durability, it meets the USA Standard specification for 606 Woodruff keys. This pack contains 10 pieces, making it a practical stocking item for shops and field service kits.

Woodruff keys of this type are used across a range of mechanical applications including HVAC blower assemblies, pump drives, compressor shafts, and general industrial equipment. The 606 designation indicates a standardized key size, allowing straightforward replacement in any application specifying a 606 Woodruff key. Machinists, millwrights, HVAC technicians, and plumbing mechanics commonly stock this size for routine maintenance and shaft-component replacement work.

Installation Notes

Installation is typically performed by a machinist, millwright, or qualified mechanical technician. Before servicing, de-energize all power to the equipment and follow applicable lockout/tagout procedures. Ensure the keyway in both the shaft and the hub are clean and free of burrs before seating the key. The key should fit snugly without requiring excessive force; an oversized or damaged keyway may indicate the need for shaft repair before reassembly.
