KRINNER foundation screws, also known as ground screws, allow for quick installation and offer structural capabilities comparable to traditional foundations and piles.
KRINNER Ground Screw Code
Each KRINNER ground screw has a structured product code that indicates its exact specifications:
- Series (KSF, KSF E, etc.) – Defines the screw type (Eccentric system, Flange, Thread fastening, Conical plastic, etc.).
- Shaft diameter (e.g., 140 mm) – The main body diameter of the screw.
- Nominal length (e.g., 1300 mm) – The total length of the screw.
- Further specification (e.g., E76, R, P, M) – Additional details such as adjustment diameter, flange type, torque, or thread design.
- Optional suffix (e.g., -100) – Number and size of lateral threads or other specific features.
This system ensures that each screw can be precisely identified and matched to its application, whether for foundations, extensions, or special constructions.
G Series
The G-series ground screws are equipped with either one, three or four threaded screws. They are ideally suited for the quick, vertical and permanent installation of masts and fence posts, for example. Optionally, the fence posts, for example, can also be quickly and permanently fixed into place with the special granulate.

E Series
The E-series ground screws can be optionally equipped with an excentre set depending on the application. The excentre set allows you to make precise adjustments and ensures a perfect, vertical positioning of the object that you want to install. The system is particularly suitable for the resonance and vibration dampening installation of poles and masts for example.

F Series
The F-series ground screws are equipped with round or square flanges. The fixation of the bearing object made possible by this ensures the highest possible stability and safety, even with large or extreme structural loads.

M Series
The M-series ground screws have a centred M-thread which allows the object that is to be carried to be directly screwed onto the ground screw. They are particularly suitable for constructing prefabricated garages and containers, for example.

V Series
Our V-series ground screws are extendable. The ground screws can be extended according to the project requirements and were specially developed for projects with high loads. The products V89, V114 and V140 come with DIBt-approval.

U Series
The U-series ground screws have been specially designed for all regularly-dimensioned timber beams. They are perfect for the simple and fast mounting of horizontal and vertical timber beams, for example during carport and wooden terrace construction.

Frequently asked questions
Ground screws are made from steel and are mostly galvanised components for foundation construction. They are driven into the ground either manually or with a ground screw driver. During the driving in, the surrounding soil is pushed to the sides and compressed. This is how the ground screw is stabilised and can bear the same loads as conventional concrete foundations.
Ground screws only work as foundations after they have been driven into the ground. For this reason, the soil composition is a crucial factor when it comes to ensuring the stability of the foundations. Our products can be used in almost all types of substrate, even in rock. However, a pre-drilled hole is needed here. Our products cannot be used in aggressive or contaminated soils. A geological survey (soil survey) can give an insight into the soil composition and the load-bearing capacity of the substrate. This must be consulted during the foundation planning. Chemical soil analyses, which are often part of the geological survey, provide important data about the aggressiveness of the soil.
