The invention discloses a corrosion-resistant internal thread type combined fastener, and relates to the technical field of fasteners. A cylindrical cavity is formed in one end of an unthreaded fastening rod, a positioning assembly is slidably connected into the cylindrical cavity, and the positioning assembly is in threaded fit with the unthreaded fastening rod; the unthreaded fastening rod is sleeved with an elastic fastening mechanism, a locking assembly connected with the elastic fastening mechanism in a clamped mode is arranged in the cylindrical cavity, and the locking assembly is in threaded connection with the positioning assembly. The positioning assembly is arranged in the unthreaded fastening rod, and after the locking assembly is inserted into the unthreaded fastening rod, the inner thread structure in the hollow positioning column on the positioning assembly is matched with the outer thread structure on the locking assembly in a threaded mode; the elastic fastening mechanism connected with the lo
