Fast answer: Threaded stems provide stronger mechanical retention. Grip ring stems install faster but rely on friction inside the tube.
Threaded Stem Casters
- Thread into insert or through-hole
- Secured with nut
- High retention strength
- Best for industrial duty
Grip Ring Stem Casters
- Press-fit installation
- Faster install
- Best for furniture & light equipment
- Relies on socket tolerances
Which Is More Secure?
Threaded stems win in side-load and vibration environments. Grip rings are best for lighter-duty, low-impact applications.
