- Precision ground to tight tolerances — oversized dimensions ensure a positive interference fit in standard keyways, eliminating backlash and play.
- Gold dichromate finish — provides corrosion resistance during storage and makes metric sizes instantly identifiable on the workbench.
- 300mm standard length — sufficient for most shaft and coupling applications, easily cut to length with a hacksaw or bandsaw.
When to Use This Product
Use this 6mm Square metric square key steel when fitting or replacing the key in a shaft keyway to lock a pulley, gear, coupling, sprocket, or flywheel. Select the key size that matches the keyway slot machined into the shaft and hub. Key steel transmits torque between the shaft and the mounted component, preventing rotation and ensuring positive drive.
