Abstract

The invention discloses a heat-treatment quenching hardened anti-theft nut with a top barrier at the top, which is a nonstandard nut in nonstandard fasteners. The anti-theft nut provided by the invention comprises a top resisting quenching hardened anti-theft nut body (1) with a top barrier at the top, a nut top (2), a nut bottom (3) and a taper wall (4) at the external circumference of the nut and the like, the nut top (2) is provided with a clockwise-screwing concave dextrorsal top barrier (211), a clockwise-screwing concave dextrorsal top barrier left barrier wall (212) and a clockwise-screwing concave dextrorsal top barrier right slope-shaped top surface (213) and the like. In conjunction with a special tool of corresponding specification and shape for assembling and disassembling theanti-theft screw, such as sleeve spanner, the anti-theft nut provided by the invention can be used for fixing and protecting a great deal of facilities which are installed outdoor and are stolen easily, such as a lamp post bottom, a wiring port cover, a cover pore and the like, from being stolen or used for distancing an old one and changing the old one with a new one, and the social benefits of the anti-theft nut are obvious.

Description

technical field [0001] The invention discloses a nut in a non-standard fastener. After it is used together with a special tool for installing and disassembling anti-theft screws, a socket wrench, etc. of corresponding specifications and shapes, it can be used for a large number of easy-to-theft facilities and street lamp posts installed outdoors. Wiring port cover cover hole carries out anti-theft fixed installation or the anti-theft installation of dismantling and replacing is used, and its social benefit is obvious. Background technique [0002] So far, there is still a lack of truly effective, easy to assemble and disassemble, anti-theft and reliable anti-theft screws and special tools for assembly and disassembly, resulting in a large number of easy-to-theft facilities installed outdoors being stolen and sold, which has caused serious damage to people's production and life. Different degrees of constraints and influences. Contents of the invention [0003] The purpose...
