The Huyett WKA-00C Woodruff key is a USA-made alloy-steel, plain-finish key for a shaft and mating component that specify this key size. Its nominal dimensions are 5/16-inch width × 1-1/8-inch diameter; the diameter describes the curved key profile, not its overall length.
Use the equipment parts requirement and the actual keyway dimensions to select a replacement. Matching two nominal dimensions alone does not establish suitability for a particular PTO, pump or driveline assembly.
| Feature | Selection guidance |
|---|---|
| Woodruff form | Match the curved key profile rather than substituting straight key stock. |
| Defined nominal size | Check both width and nominal diameter against the required key. |
| Plain-finish alloy steel | Confirm that the equipment calls for this material and finish. |

| Equipment specification | Confirm the specified material, finish and key form for the exact assembly. |
| Replacement identity | Use WKA-00C and the equipment parts requirement; do not assume interchange from size alone. |
