Service HotlineIn view of this, a screw with waterproof, anti-loosening and anti-removal functions is provided. A screw comprises a screw rod and a screw head connected with the screw rod, the diameter of the screw head is larger than the diameter of the screw rod, and an annular groove is formed around the screw rod on the surface of the screw head connected with the screw rod, The screw head is also provided with a through hole penetrating the screw head, and the through hole is communicated with the annular groove for filling the annular groove with adhesive substances. Compared with the prior art, the screw provided by Guangdong Yueluo Hardware Industry Co., Ltd. has a structure in which a through hole and an annular groove are arranged on the screw head, so that after the screw is locked into the screw hole, the screw head is not locked. A glue storage flow channel is formed between the contact surface with the part, and then the glue material is injected into the glue storage flow channel through the through hole to form a sealing annular rubber ring, so as to better ensure the waterproof performance of the screw joint. Furthermore, by connecting the through hole with the screwdriver groove, while forming a sealing annular rubber ring, the driver groove can be directly filled for the purpose of preventing dismantling.
During assembly, the washer and the screw are two separate parts, and the washer needs to be put on the connection part of the screw, which increases the workload of people during assembly, and the washer is easy to slip off; and some screws are fixed with Although the washer can reduce the workload of people during assembly, the washer is fixed on the screw, and the original function of the washer is limited.
The fastener with a nut is composed of a polygonal nut and a bolt. The bolt includes an integral screw rod and a screw head. The fastening surfaces of the nut and the screw head are polygonal. There are external threads on the periphery of the screw, and the main point is that the axial three-dimensional shape of the nut and the screw head is an odd-numbered truncated cone, and the odd-numbered angle is an arc angle, and each arc angle corresponds to an elastic surface.

Yueluo is about a special fastener and its screwdriver. That is, the Y screw and its screwdriver. In order to prevent the leakage of new product manufacturing technology and prohibit others from arbitrarily opening the shell of the new product or disassembling the relevant parts, it is necessary to take effective precautions against their own products, and the use of special fasteners is one of the purposes of Yueluo. This kind of screw can also be widely used in the fixation of some public equipment, for the fastening and fixing of parts that are afraid of disassembly and theft, so as to play a certain protective role.
