Can screw jacks be permanent?
Yes, screw jacks can be used as both temporary and permanent supports, depending on the specific type of jack and its installation. They are often used for permanent support in structural repairs and as secondary supports, but they must be installed correctly and, in some cases, permanently disabled from their adjustment mechanism.
Temporary uses
Relieving stress on a building during repairs, Shifting a foundation wall, Supporting a structure during excavation, and Providing temporary support in emergency shoring.

Permanent uses
- As supplemental support for a main beam in a basement
- Holding a steel I-beam in place
- Replacing makeshift columns
- In permanent shoring for certain projects
Important considerations for permanent use
- Ensure proper installation to prevent future issues like rust.
- For some types of jacks, the adjustment mechanism may need to be rendered permanently inoperable, such as by welding the threads or burying it in concrete, to prevent future adjustments.
- Some hollow, thin-walled jacks may not be suitable for permanent use, as they are more vulnerable to rust and are not designed for long-term heavy pressure.
- Always use the appropriate type of screw jack for the job, as some are specifically rated for permanent use and others are not.
