Anchor Screws
Projects, firmly anchored.
Graewe anchor screws and double ends are robust fasteners for secure anchoring and force-locking connections under static and dynamic loads. They are used in particular for concrete and foundation anchors, in steel and metal construction and in mechanical and plant engineering. As a rule, these are custom-made special versions that are manufactured to fit perfectly — for long-termstability.
Graewe offers anchor screws and double ends for a wide range of applications. The products can be divided into two main groups:
Double ends with external thread on both sides:
A round bar with external thread on both sides and a smooth shaft allows screws from both sides — ideal for flange-based connections, foundation baskets and steel structures. Also known as anchor bolts or foundation anchors.
Anchor screws with one-sided thread:
This variant has a one-sided external thread and a smooth or shaped shaft. It isembedded in concrete, embedded or welded and is used, for example, to securemachines, steel or building structures to concrete foundations.
Many versions are manufactured individually according to customer drawings —variable in thread type, material, strength class, surface, length and diameter.
- Threa ddiameter: M8 to M72
- Fixed lengths: up to 6,000 mm
- Steel: 4.8, 5.6, 8.8, 10.9
