Summary of information:We have more than ten years of experience in the production of screw industry, the main products are: double-sided obliq...

The two combination screws are classified according to the national standard, including GB9074.2, GB9074.3, GB9074.5, etc. GB9074.3 refers to a two-component combination of a cross pan head screw and a foreign lock washer.

Screws can be divided into machine screws, self-tapping screws, drill-tail screws, wallboard screws, fiberboard screws, wood screws, hexagonal wood screws, non-prolapse screws, combination screws, miniature screws, furniture screws, and electronic screws. Divided into 1. Hexagon head (hexagon head) 2. Hexagon head with flange (hexagon head with flange) 3. Square head (square head) 4. T head (hammer head) 5. Oblate head mushroom head ( truss head) 6. cylindrical head (cheese head) 7. round head (round head) 8. pan head (pan head) 9. countersunk head (flat head) 10. raised countersunk head (oval according to the groove type) Can be divided into 1. Philip 2. Ten / one word 3. One word 4. Inner triangle 5. Inner corner square 6. Cross 7. Rice word 8. Flower shape 9. Plum shape 10. Flower shape one word 11. Special shape 12. Inside Hexagon

How to use, what is a rivet nut? Usually, rivet nuts used inside elevators are used to install some kind of screws when installing various parts on cars or individual boards on aviation. Commonly used places are very important connection parts, so the choice of rivet nut material is very important. How to use the rivet nut? Let's watch it together. Rivet nuts are used in the fixing fields of various metal plates, pipes and other manufacturing industries, and are widely used in the assembly of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, and decoration. It is designed to solve the shortcomings of sheet metal, thin-walled pipe welding nut, substrate welding deformation, internal thread taper, etc. It does not require internal thread, welding nut, rivet efficiency, and is easy to use.

Here Yueluo eliminates the drawbacks. The purpose of Yueluo is to provide a locking screw by which the gap existing between the locking screw and a transverse hole in a locking screw can be eliminated. Yueluo achieves the proposed object with a locking screw, which has the features of claim 4 . The line connecting the centers of gravity of the respective axially continuous orthogonal cross-sectional areas of the locking screw is regarded as a line. The advantage achieved by Yueluo can basically be seen that, due to the locking screw of Yueluo, the gap between the horizontal hole of the screw and the locking screw can be eliminated. Other advantages are as follows - the insertion accuracy and surgeon time spent remain within the range to date; - the strength of the locking screw is maintained; and - the extraction of an expired broken screw is assured. The further composition of Yueluo and Yueluo is explained in more detail below by means of schematic diagrams of parts of various embodiments.

The utility model relates to a connecting piece, in particular to a female and female screw used for shaping products in interior decoration. In the current decoration project, when fixing the decoration stereotyped product, the process is complicated, so labor-intensive and time-consuming, the construction cost is high, and the construction degree is low. For example, the decorative board for fixing the wall, the main process step used in its operation is the leveling of the nail strip. That is to say, saw the wood to the required specifications, then draw horizontal and vertical lines on the wall, and then nail the wooden strips to the wall according to the horizontal and vertical lines, and then glue and glue the board. The first step is to install the lines, color and paint. It can be seen that it is quite troublesome to use the above method to construct. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a female screw, which can skillfully connect decorative products to the wall. As conceived above, the technical solution of Guangdong Yueluo Hardware Industry Co., Ltd. is a female screw, which is characterized in that both ends of the screw are threaded, the screw-in end is screwed into the plastic expansion tube inserted into the wall, and the other end of the screw is threaded with the same A female piece is mated and connected. The other end of the screw can also be barb-shaped and directly fit with the decorative board. The screw thread of the screw-in end is a wood thread, and the thread of the mating connection end with the female part is a machine thread.
