Threaded rod hangers are used to suspend threaded rod from concrete slabs and wood or steel beams in order to hang pipes, cable tray, HVAC equipment, and many other construction materials. Threaded rod hangers are high-strength screw anchors.
The wood rod hanger from Simpson Strong-Tie is a one-piece fastening system for suspending 1/4" or 3/8" threaded rod. Vertical rod hangers are designed to suspend threaded rod in overhead applications from wood members. Horizontal rod hangers are available for applications requiring installation into the side of joists, columns, and overhead members. Both rod hangers provide attachment points for use in pipe hanging, fire protection, electrical conduit, and cable-tray applications. These anchors are recommended for use in dry, interior, non-corrosive environments only. Outpost sells a wide variety of Simpson products, including threaded rod hangers such as the ones shown in figure (1) below.
The DeWalt Hangermate concrete screw is a one-piece, steel anchor designed for rod hanging applications such as fire protection systems, ventilation systems, electrical conduit, pipe hanging, and cable trays. These anchors have been tested and qualified for use in cracked concrete and seismic conditions. These anchors require masonry bits for installation, and typical uses are for 1/4", 3/8" or 1/2" diameter threaded rods.

Another secure way to hang threaded rod from a pair of angles, such as those used in ceiling joists, without the need to drill or weld, is by using threaded rod clamps/clips. These hangers are commonly used to suspend HVAC, conveyor, and other overhead systems. They may also be used to connect two pairs of angles at 90°. Figure (2) shows how threaded rod clamps/clips are typically used.
