anchor nut/domed nut for rock bolt
Product Introduction
A threaded bar can be used as a ground anchor by drilling a hole into the ground and inserting the bar deep enough to provide sufficient stability for whatever is being anchored. This could be anything from a small tent or canopy to a large sign or billboard. The bar is typically secured in place with concrete, soil, or other materials that provide enough friction to prevent it from being pulled out of the ground by force. Depending on the weight and size of the structure being anchored, multiple bars may be needed to ensure the necessary strength and stability.
Fully threaded steel bars are currently used to anchor and support the dam body form of the dam foundation. In the cable-stayed bridge, fully threaded bars are used as the main ribs and bridge foundations of the main tower. The use of fully threaded steel bars saves steel, reduces component area and reduces component weight.
The continuous external thread is hot rolled. The shape of thread bar is shown as following figure. The main dimension ranges from ⌀15mm-⌀50mm and the grade ranges from 500/630Mpa to 1200/1330Mpa.
