Anti-theft nut structure

The introduction of anti-theft nuts has brought significant benefits to public infrastructure and the safety of both personal belongings and property. These innovative fasteners are now widely used across various applications, offering a reliable solution against unauthorized removal. The main objective of this invention is to provide a coupling mechanism that securely connects components without any movement or loosening. The design features a resin plate 50 with a locking receiving portion 51 that includes a locking hole 52. On the door edge 30, a locking arm 41 is integrated, which has a locking claw 43. This claw can be inserted into and fixed within the locking hole 52. To enhance security, a crush wall 45 is placed on the opposite side of the locking arm from the locking claw. When the locking arm is inserted into the locking hole, the crush wall exerts pressure, causing the hole to expand slightly. During insertion, the crush wall compresses the inner wall 52A of the locking hole. Once fully inserted, the crush wall forms a secure, interlocking structure by biting into the inner wall, ensuring a tight and stable connection between the resin-molded parts. In addition, the invention also introduces a general-purpose fastening screw designed for ease of use. This screw features a tapered tail, an axial groove along its shaft, serrated threads on the grooved section, and a driver slot on the head. These features make it easier to drive in and remove, while preventing the screw from backing out due to vibration or impact. This makes it ideal for use in environments where stability and durability are essential. Overall, these innovations not only improve the functionality and security of fastening systems but also contribute to safer and more reliable installations in a wide range of applications.
