screw fs-750-f®

The service life is measured in terms of years before any maintenance of the galvanization is required.

Obviously, this depends on the environment in which the screw is installed.

• In less aggressive environments, the service life is between 35 and 50 years.
• In marine environments, the service life is between 9 and 11 years.

For more information, you can find tables listing the different thicknesses and types of environment below:

The WeasyHead must remain attached to the foundation screw until the foundation screw has been driven into the ground in order to transmit all the energy from the installation machine to the foundation screw.

Therefore, ideally, it should be attached using a small impact driver.
If you do not have one, you can use a hand impact driver

Foundation screws are perfectly suitable for installing in fresh water and sea water.

A distinction must be made here between two cases:

• The installation is carried out in shallow water: an installation machine that does not require a specific tool can be used. As the Toku MI4500 is pneumatic, there is no risk of electrocution.
• The installation is carried out in deeper water: the pneumatic machine must be adapted to the work carried out underwater.
