Fasteners are the most widely used and widely used mechanical basic components in various sectors of China's national economy, known as the "rice of industry". In the past 30 years, with the rapid development of the metallurgical, mechanical, and electronic industries, the global faste...

Stamped parts are mainly made of metal or non-metallic plates through stamping molds under the pressure of a press, and have the following characteristics:Stamped parts are formed by stamping with minimal material consumption. Its parts are lightweight and have good stiffness. After plastic deformat...

1. First measure the location where drilling is required and mark the location with a pencil.2. Based on the size of the expansion screw you are using, choose a suitable drill bit (the diameter of the drill bit is the same as the diameter of the expansion pipe), and use a hand electric drill to dril...

1. Strong resistance to deformation. Compared with ordinary steel plate stamping fasteners, due to different manufacturing processes, it breaks through the limitations of traditional stamping processes on material thickness (stamping processes can only reach the thickness limit of 3.5mm, which is ea...

Spring washers are used for anti loosening, while flat washers do not have anti loosening function. Flat washers can only increase the contact area. Flat washers are only used to increase the contact area, and spring washers can prevent loosening. For example, the bolts connecting the motor and...

Environmental protection, energy conservation, and safety are also known as the three main themes of the fastener industry. The rapid development of China's fastener industry has brought enormous economic benefits and social wealth to society, while also causing corresponding environmental pollu...

Titanium and its alloys have low density (4.51g/cm3), high strength (some up to 1000MPa), high strength, and excellent high and low temperature properties. They are widely used in industries such as aviation and aerospace, and have become indispensable structural materials in the military industry....

1. The large hexagonal high-strength bolt must be a screw, two washers, and a nut used together;2. Torsional shear high-strength bolts must be a screw, a washer, and a nut used together;3. High strength bolts such as engine cylinder heads must be used together with a screw, a washer, and a nut;The s...

Double headed bolts are used for large equipment such as reduction frames. In practical applications, external loads can cause vibration and temperature effects, resulting in reduced friction. Over time, threaded connections will become loose and fail. Therefore, it is necessary to maintain the doub...

1) The content of boron can reach 0.005%, and its non effective boron can be controlled by adding titanium and/or aluminum.2) These performance grade stainless steel nuts allow for easy cutting manufacturing, with a maximum content of sulfur, phosphorus, and lead of 0.34% sulfur; Phosphorus 0.11%; 0...

1. Save time. In the traditional screw fixation process, workers need to first place the screw on the head of the batch before fixing the device. However, using chain screws can eliminate this step and greatly shorten construction time. According to data from the United States, using chain screws ev...

Connecting rod composition. This type of fastener is widely used in industries such as construction, machinery, and equipment manufacturing.
