Abstract
The invention discloses an anti-theft screw with a butting bar on a screw hole top in a heat treatment stiffening screw top, which is an anti-theft screw for a non-standard fastener. The anti-theft screw comprises a heat treatment quenching stiffening screw body (1), a top surface (4) of a screw top and the like, wherein at least one dextrorotation recessed butting bar (14) which is screwed in the top surface of the screw top in the clockwise direction or at least one levorotation recessed butting bar (24) which is screwed in the top surface of the screw top in the anticlockwise direction is arranged on the top surface (4) of the screw top. After the anti-theft screw is matched with tools such as movable sleeves, ratchet handle wrenches and the like which have corresponding specifications and shapes, are used for assembling and disassembling two profiled threads and are provided with the butting bar screws on the screw tops, a large number of wiring opening covers in the bottom sections of lamp poles arranged outdoors can be subjected to anti-theft arrangement or replacement, so the anti-theft screw has obvious social benefits.
