The threaded end of the wedge anchor protrudes from the surface of the concrete once it is installed, and is the area of the wedge anchor that is being struck with a hammer. Care must be taken not to damage the threads during installation. If proper care is not taken, the threads will be damaged and the nut will lose the ability to be put on or taken off. All threads on wedge anchors are national coarse threads for each diameter. The larger the diameter of wedge anchor being installed, then the larger and heavier the hammer must be.
When installing a wedge anchor, the nut must be threaded on the threaded end of the wedge anchor so that the top of the nut is even with the top of the wedge anchor body. When threading the nut on correctly, the threads will be protected during installation and allow the nut to be removed and then threaded back on. Many wedge anchors are manufactured with a bullnose. This bullnose is a protrusion that extends above the threads with the purpose of having a surface for the hammer to strike without damaging the threads. Although the bullnose feature works very well, it is advised to thread the nut onto the wedge anchor as a precaution to ensure that the threads are not damaged by the hammer strike.
