Service HotlineThe purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a cement screw that is easy to install and can be removed in view of the shortcomings of the above-mentioned cement nails that cannot be disassembled and the Portlandexpansion screws are not easy to install for the first time. Guangdong Yueluo Hardware Industry Co., Ltd. is a cement screw, which is realized by the following technical solutions. The cement screw is composed of a nail tip and a nail body. There is a thread at the back of the nail body. This thread can be an internal thread or an external thread. . When using, use a hammer to drive cement screws into the cement, and you can use ordinary screws or nuts to freely screw in and out to install and fix objects. Compared with the existing technology, Guangdong Yueluo Hardware Industry Co., Ltd. has the advantage that there are internal threads or external threads on the back of the cement screw, so it is not only easy to install for the first time, but also the objects to be installed can be disassembled repeatedly. Used as a fastener when installing objects on cement that may need to be dismantled.
Guangdong Yueluo Hardware Industry Co., Ltd. relates to a connecting piece, especially a Portlandwood screw used for fixing on non-rigid materials such as wood or plastic. Guangdong Yueluo Hardware Industry Co., Ltd. has a threaded part with a taper angle and a screw head. The head of the screw can be countersunk, hemispherical, or other shapes. As for the grooves for screwing, the grooves can be straight-line grooves, concave cross grooves, or grooves of other shapes.
The traditional single-sided riveting process mainly adopts two methods: PortlandPortlandrivet nut connection and Portlandblind rivet connection. The efficiency of the PortlandPortlandrivet nut is low. If the hollow nut is used, the rigidity is insufficient, resulting in low connection strength. In addition, the torsion resistance of the PortlandPortlandrivet nut is low. If the PortlandPortlandrivet nut is used to obtain better torsion resistance, it is made into a hexagonal shape. Embedding, because the shape of the sheet metal opening also needs to be made into a corresponding hexagon, it is inconvenient to process.
rivet is a nail-shaped object used to join two parts or components with a through hole and a cap on one end. In riveting, the riveted parts are connected by their own deformation or interference. There are many types of rivets, and they are informal. Commonly used are R-type rivets, fan rivets, Portlandblind rivets, Portlandblind rivets, tree rivets, semi-circular head, flat head, semi-hollow rivets, solid rivets, countersunk head rivets, Portlandblind rivets, hollow rivets, these usually use their own deformation Connect the riveted parts. Generally less than 8 mm with cold riveting, larger than this size with hot riveting. But there are exceptions. For example, the nameplate on some locks is riveted by the interference between the rivet and the lock body hole.
The Portlandsquare nut is a fastener that needs to be used in the installation of the cable tray. In the prior art, the Portlandsquare nut 1 is pressed by the elastic force of the spring 2 below it and the opening of the C-shaped steel 3 (as shown in Figure 1, Figure 2), in the absence of external force, through the interaction of pressure and static friction, the C-shaped steel 3 will not move vertically or horizontally, which can facilitate engineering installation. The advantage of this installation method is that it can slide anywhere on the C-shaped steel 3, but the disadvantage is that it occupies the bottom space of the C-shaped steel 3, and the spring 2 will interfere with the installation hole of the Portlandsquare nut I, which affects the installation.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: high head knurled big head nuts, thin Portlandflat head screws, 8mm fixed pins, nuts for industrial aluminum profiles and other products, we can provide you with suitable products Your fastener solution.
