Products Description

A double threaded rod is a rod-like part with two threads. This design is not only more robust when connecting two objects, but also easier to disassemble and maintain. In the case of an isotropic thread, when rotating, the mating part will make a linear movement in the same direction along the axis of the rod, and the speed of movement will be faster compared to a single thread. This is very practical in some mechanical devices that require symmetrical movements at the same time. In large-span steel buildings, double-threaded rods can be used as the key components of connection nodes.
