The hinge is a hinge, which is often composed of two folds. It is a part that connects the two parts of the object and can make it move. The hinge supporting screws are installed on the corresponding objects. For different use environments, the requirements for the supporting screws are also different. different. Most of the existing screws are set to a single-threaded structure. When used to cut into a wooden door, the cutting speed is slow, and the cutting effect is not ideal, which is not conducive to cutting into a hard wooden door, etc., and the commonly used screws are often made of iron materials. It is easy to rust after contact with water vapor, reducing the service life; in addition, when the screw is driven into the wooden door, the chips generated cannot be discharged in time, and stay inside the wooden door and surround the screw, forming expansion stress, thereby squeezing the wooden substrate, which is not conducive to the screw. The connection with the wooden door is stable, which easily affects the normal installation of the hinge, and the use effect is poor. To sum up, in order to solve the shortcomings of the existing screw structure for hinges, Guangdong Yueluo Hardware Industry Co., Ltd. designed a hinge screw with simple structure, convenient use, fast construction and good effect.

With the rapid development of China's machinery industry, especially the development of heavy industry, the demand for large-scale metal processing equipment is increasing; at the same time, higher requirements are also placed on the technical parameters of the equipment. For some large-scale CNC equipment, to ensure the machining accuracy of the whole product, it is not only necessary to rely on high-performance components such as full closed-loop control and precision transmission components, but also requires the positioning and stability of the joint surfaces between the large and medium-sized components of the equipment. The common positioning of the joint surface between large components adopts flat key positioning, and this method requires processing the keyway at the joint surface of the large components. Since the joint surface of large parts is affected by factors such as processing and splicing, it cannot guarantee that the keyways on the large parts combined can be matched according to the theoretical requirements. Therefore, the positioning flat key needs to press the flat key in the two parts of large parts. Different repair allowances Trim into a stepped shape. The height difference of this keyway in different large components makes a single flat key need to be repaired on four sides, which increases the difficulty of the key repair process and makes it difficult to improve work efficiency. Not only that, when the flat key is repaired and assembled, it must be in an interference fit with the keyway, which makes the disassembly and assembly of the flat key more laborious.

Rivets are mostly used for fixed riveting and movable riveting between parts. The rivets used for movable riveting are mostly cylindrical, and there is no size limit for riveted parts, which is easy to cause parts to be squeezed and deformed during riveting. For example, The parts are inserted into the parts for active riveting. When riveting, the riveting force can easily cause the parts to clamp the parts, which in turn causes difficulty in the movement of the parts and the parts, high operating force and noise problems, and the parts are easily damaged.

At present, in the field of building curtain wall, factory building support structure, shelf structure and other fields of steel structure connection, if closed profiles (such as rectangular steel pipes) are used as the connection structure, welding connection is generally used, and bolt connection cannot be realized. The reason why a bolted connection is not possible is that the profile is a closed structure and it is not possible to place the bolt at the connection location because the size of the bolt head is larger than the thread hole diameter on the profile. Welded connections affect the structural quality of outdoor projects, with poor corrosion resistance, reduced structural strength, and frequent fire accidents. However, the existing non-welded steel structure and the fastening connection of the bracket have complicated T-bolt structure, troublesome processing technology and high production cost.

Stainless steel screws, as the name suggests, must be made of stainless steel screw wire, and then screw the screw thread. Many of the properties of stainless steel screws are related to stainless steel. Taking into account the properties and organization of stainless steel, understand the properties of stainless steel materials and other aspects. Therefore, it is understood that stainless steel has good mechanical properties such as anti-rust, anti-corrosion, high temperature resistance, etc., then stainless steel screws also have these good mechanical properties. With the increasing quality of stainless steel materials. The mechanical properties of stainless steel screws produced by the screw industry are getting better and better. Anti-rust, anti-corrosion ability, and high temperature and high pressure are getting stronger and stronger.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: flat washers, meson washers, white zinc plated hexagon bolts, round head cylindrical pins, hexagonal square welding nuts and other products, we can provide you with suitable products Your fastener solution.
