The invention discloses an anti-theft bolt which comprises a screw rod and a screw cap. A cylinder-shaped first groove is formed in the top surface of the screw cap. A clamp joint is arranged at the bottom of the cylinder-shaped first groove. A seal cover is mounted in the first groove in the upper part of the clamp joint through a thread. A second groove used for yielding the clamp joint is formed in the bottom surface of the seal cover. A cylinder-shaped third groove is formed in the top surface of the seal cover. A stripped fourth groove extending in the axial direction is formed in the wall of the third groove. The invention further discloses a disassembling tool for the anti-theft bolt. The anti-theft bolt and the disassembling tool have the beneficial effects that the groove is formed in the top surface of the screw cap, the seal cover is arranged in the groove, and is only disassembled by a special tool, an unconventional disassembling structure is adopted, the seal cover is opened by the special disassembling tool matched with the unconventional disassembling structure, the bolt is screwed by a wrench matched with the clamp joint, and the anti-theft performance of the anti-theft bolt is remarkably improved.
