Industrial Feather Keys (Precision Guide Keys)
Feather Keys are designed to allow a hub to move axially along a shaft while still transmitting torque. Unlike standard parallel keys, feather keys are usually fastened into the keyway of the shaft or hub using screws, acting as a guide or track for sliding components.
Core Advantages
- Axial Flexibility: Perfect for clutches and shifting gears that need to slide while rotating.
- High Precision: Finished to h9 or h7 tolerances to ensure smooth sliding motion without backlash.
- Durable Construction: Available in heat-treated carbon steel for maximum service life.
Feather Keys Specifications
| Width (mm) | Height (mm) | Fixing Holes |

| 20 – 40 | 12 – 22 | 2+ Countersunk |
FAQ
Q: How are feather keys secured?
A: They are typically secured via countersunk screws into the shaft’s keyway, preventing the key from moving while the hub slides over it.
