The invention relates to a double-ended threaded fastener, a method for manufacturing the same and a special tool, which belong to the technical field of hardware tools and overcome the defects of low efficiency of mounting and demounting, short service life and high use and maintenance cost in the prior art. The double-ended threaded fastener refers to a bolt and a nut, and is characterized by comprising a fastener main body provided with a threaded part, wherein the threaded part has a double-line thread structure, two threads are evenly distributed alternating with each other, and the thread diameter and the thread distance are same. The manufacturing method comprises the following steps: (I) manufacturing a core rod; (II) manufacturing a screw plate; (III) manufacturing a screw tap; and (IV) producing the double-ended threaded fastener on a machine tool for making the fastener by using the screw plate and the screw tap. The double-ended threaded fastener produced by a novel manufacturing method has a double-line thread structure, thus the mounting and demounting time is reduced, the strength is increased, the working efficiency is improved, the service life is prolonged, and the cost is greatly saved.

The invention discloses a fast high-precision locating unit. The fast high-precision locating unit comprises a central spindle, a protecting jacket, a pan head screw and a plurality of steel balls with the same diameter. A step is arranged in the middle of the central spindle and divides the central spindle into an upper locating section and a lower locating section. The step is provided with a countersunk head screw hole. The inner surface of the protecting jacket is provided with an annular groove in the circumferential direction. The width D3 of the annular groove is slightly greater than the diameter D1 of each steel ball. A plurality of through holes are formed in the bottom of the annular groove. The diameter D4 of each through hole is slightly smaller than the diameter D1 of the corresponding steel ball. The upper locating section of the central spindle is sleeved with the protecting jacket.
