MIDWEST FASTENER 60923 Woodruff Key
The MIDWEST FASTENER 60923 is a semicircular steel key designed to lock pulleys, gears or other components onto a shaft. It fits a matching keyway and prevents unwanted rotation in automotive and machine-tool assemblies. Mechanics and maintenance technicians use it when rebuilding or repairing drives that require a standard woodruff profile. The part is supplied new and ready for installation.
Replaces a worn or sheared half-moon key
When an existing key has deformed, rounded or snapped, this replacement restores the positive drive between shaft and mounted device. The jump is worth it if the original keyway dimensions match the 1/8 x 1/2 inch profile and the application calls for a No. 3 SAE woodruff key. It does not suit shafts cut for larger, smaller or differently numbered woodruff sizes, nor does it replace parallel or taper keys.
Check the shaft keyway and component slot
Verify that the shaft keyway and the mating component slot both accept a No. 3 SAE woodruff key with a 1/8 by 1/2 inch cross-section. Confirm the shaft material and keyway condition are sound enough to hold the steel key without excessive play. Orders of $75 or more ship free from the manufacturer.

Questions about this item
What shaft keyway dimensions does the 1/8 x 1/2 in woodruff key fit?
The key fits a semicircular keyway cut to a 1/8 in width and 1/2 in diameter, leaving a protruding tab that engages the mating slot on the mounted component.
How do you install the woodruff key so it seats fully in the keyway?
Align the flat face with the shaft axis, press the key into the keyway until the curved surface bottoms out, then slide the pulley or gear onto the shaft so its slot engages the protruding tab.
When should the steel woodruff key be inspected or replaced?
Inspect the key whenever the mounted component is removed; replace it if the tab shows rounding, shear deformation, or if the keyway walls exhibit widening from fretting.
