Description

technical field [0001] The invention relates to an anti-theft bolt, in particular to an automobile anti-theft bolt, which belongs to the technical field of fasteners. Background technique [0002] In order to protect their own interests, merchants often use anti-theft bolts on their products. At present, most anti-theft bolts use conical external threads and special tools, which can only be tightened clockwise, and the tool will fall off when disassembled by counterclockwise force. Anti-theft unloading effect; in the automobile manufacturing industry, the anti-theft of tires usually uses some bolts with special-shaped ends, and a special wrench is used for disassembly to achieve the purpose of anti-theft. [0003] However, as a kind of fastener, anti-theft bolts also need to be mass-produced. Whether it is an anti-theft bolt with a tapered end or an anti-theft bolt with a special shape at the end, they all have a common feature after mass production, that is, use the same a...

Problems solved by technology

[0003] However, as a kind of fastener, anti-theft bolts also need to be mass-produced. Whether it is an anti-theft bolt with a tapered end or an anti-theft bolt with a special shape at the end, they all have a common feature after mass production, that is, use the same anti-theft bolt. Wrench can disassemble all the bolts of this specification batch at the same time. When the thief is familiar with the types of anti-theft bolts in a certain field and prepares a wrench of a certain specification, these anti-theft bolts will no longer be able to prevent theft.
