Standard threads are a continuous inclined plane that can clamp anywhere along its length. Van Cor Threads look like threads and screw together like threads but are a very complex wedge where all surfaces engage at the same time within a specific clamp length. The inherent aspect is repeated precision positioning. That allows multiple layers of connecting electrical, electronic, optic points can be nested within a threaded body. The same for fluid or pneumatic channels. These can be mixed and bundled within a structural application such as a robotic arm.
An image of what a ribbon cable following a wave thread contour would look like. In practice it would be of diminishing size from the large top to bottom as each cable ends with an exposed point that the mating point will align with.
