The utility model discloses a copper double-end stud, and belongs to the technical field of mechanical joint elements. The copper double-end stud comprises a copper stud main body, a first stud and a second stud, wherein the first stud and the second stud are cooperatively arranged at the two ends of the copper stud main body; a stopping column is arranged on an end socket of at least one of the first stud and the second stud; the copper stud main body is an irregular cylinder structure; the cylinder surface is composed of two parallel plane parts and two arc-shaped surface parts which are respectively connected with the two sides of the two plane parts. According to the utility model, the copper stud main body is of the irregular cylinder structure formed by the two parallel plane parts and the two arc-shaped surface parts connected with the two sides of the two parallel plane parts respectively, in the screwing process, the two plane parts can be clamped by a pair of pliers, and the copper double-end stud can be screwed in, so as to effectively prevent slipping and meanwhile ensure the tighter screwing effect; furthermore, the stopping column is arranged on the end socket of at least one of the first stud and the second stud, so that the situation that the threaded root part of the stud is completely screwed in a threaded hole of a part main body can be avoided, the powerful stress subjected to the threaded root part can be reduced, further the working strength of the copper double-end stud can be strengthened, and the service life can be prolonged.
