Summary of information:We have more than ten years of experience in screw industry production, the main products are: hexagonal flange fine thr...

The retaining ring is divided into two types: shaft use and hole use. Its structural characteristics: The shaft retaining ring is a kind of retaining ring installed on the shaft groove, which is used for positioning and fixing of shaft end parts, and can withstand severe vibration and shock loads, but It is necessary to take anti-loosening measures and installation positioning; the hole is installed in the circular hole with an elastic retaining ring, which is used for the axial movement of the fixed parts. The outer diameter of this retaining ring is slightly larger than the diameter of the assembly circular hole.

Most of the electroplating used for rivet nuts on the market is environmental protection blue zinc, because the salt spray test time of environmental protection blue zinc can reach 72 hours, that is, three days. This kind of electroplating has a longer salt spray resistance time. In fact, for example, for electroplating white nickel, the salt spray time of white nickel is relatively short, and it usually rusts in a few hours, which is less than 10 hours. However, some can be oiled for electroplating white nickel, and the salt spray time of the rivet nut after oiling can be longer. S series rivet nuts are made of free-cutting iron, which is treated after heat treatment. CLS series rivet nuts are made of easy-to-cut stainless steel. The hardness of low-carbon steel plates without surface treatment must be less than 70RB, and the hardness of stainless steel plates must be less than 80RB.

In view of the deficiencies of the prior art, Guangdong Yueluo Hardware Industry Co., Ltd. provides a relatively simple screw that can be manually disassembled. In order to achieve the above purpose, Guangdong Yueluo Hardware Industry Co., Ltd. provides the following technical scheme: a screw that can be disassembled manually, including a stud and a nut, and the axial direction of the screw is provided with a screw extending from the nut to the stud. A groove, a control column that is slidably matched with the groove is arranged in the groove, a through groove is opened on the circumferential side wall of the control column, and a circumferential side wall of the control column is provided with a parallel to the axis of the control column. A limit bar, the side wall of the groove is provided with a limit groove that cooperates with the limit bar, the control column is provided with a accommodating groove, and the accommodating groove is provided with a rotating rod that cooperates with the through groove, so The accommodating groove and the rotating rod are arranged separately. Further, a accommodating groove is opened at the corresponding groove on the nut, a baffle is hinged on the side wall of the accommodating groove, and a torsion spring is provided at the hinged joint between the baffle and the accommodating groove.

screw suitable for a variety of tools is a single-structure threaded part, including a screw body and a screw head. The outer surface of the screw body is processed with an external thread 1, and the outer side of the screw head is formed by six screw heads. Prismatic, the top surface of each edge of the outer hexagonal prism is a boss, between each boss is an end face groove 4, and the middle of each boss is provided with an end face hole 3; the inner side of the screw head is formed by six screw heads. The side surface 5 forms an inner hexagonal prism hole, and the bottom of the inner hexagonal prism hole is processed with a cross groove 12 .

It is used for fastening in the machinery, construction and electrical industries. One end is a hexagonal head for wrench tightening, and the other end is a thread. According to different thread lengths, it is divided into full thread and half thread, abbreviated as: GB bolt.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: red handle screws, enlarged bolts, single-head hexagon stud bolts, fisheye washer screws and other products, we can provide you with suitable products for you. Fastener Solutions.
