I believe you have a certain understanding of fasteners, but you may not know so much about the threads of fasteners. The following is the use and classification of fastener threads. Let’s take a look with China Stud Supplier.

       Threads are used in a wide range of applications, from airplanes and automobiles to water pipes and gas used in our daily lives. Most threads play a role in fastening connections, followed by the transmission of force and motion. There are also some special-purpose threads. Although there are many types, the number is limited. The durability of the thread is due to its simple structure, reliable performance, convenient disassembly, and ease of manufacture, making it an indispensable structural element in various electromechanical products today. According to the purpose of the thread, all kinds of threaded parts should have the following two basic functions: one is good screwability; the other is sufficient strength.
       The threads of Industrial Bolt Factory can be divided into: metric thread (metric thread), inch thread, American thread, etc. according to the region (country). We are used to refer to the inch thread and the American thread collectively as the inch thread, and its profile angle is 60°, 55°, etc., the related thread parameters such as diameter and pitch adopt inch size (inch). In our country, the tooth profile angle is unified to 60°, and the diameter and pitch series in millimeters (mm) are used to name this type of thread: ordinary thread. The above is the basic knowledge of fastener threads introduced by the editor today, I hope it will be helpful to everyone. Our company will serve you wholeheartedly, waiting for your call or visit at any time.

        What are the surface treatment amplification of standard parts? It is not unknown to people in this industry. Today zhejiang weigao Industrial Bolt Factory will give you a brief introduction to the surface treatment methods of standard parts:

       1. Electroplating of standard parts

       Standard part plating refers to immersing parts of fasteners that need to be plated into a specific aqueous solution. The aqueous solution will contain some deposited metal compounds. In this way, after passing current through the aqueous solution, the metal substances in the solution will precipitate out and adhere to the tight The immersion part of the firmware. The electroplating of standard parts generally includes zinc plating, copper, nickel, chromium, copper-nickel alloy, etc.

       2. Hot dip galvanizing of standard parts

       The hot dip galvanizing of the standard parts is to immerse the standard parts of carbon steel components into the molten zinc plating bath with a heat of about 510°C, so that the iron-zinc alloy on the surface of the standard parts will be converted into passivated zinc to obtain surface treatment effect. The price of hot dip galvanizing for standard parts is higher than that of electroplating.

       3. Mechanical plating of standard parts

       The mechanical plating of standard parts refers to the use of specific physical and chemical means to impact the surface of the fastener with the powder of the coated metal, so that the coated metal forms a coating on the surface of the fastener by cold welding to achieve surface treatment effect. The mechanical plating of standard parts is mainly suitable for spare parts such as screws, nuts and washers.

       The main purpose of the surface treatment of China Stud Supplier standard parts is to make the fastener itself obtain anti-corrosion ability to increase the reliability and adaptability of the standard parts. Therefore, the quality judgment of the surface treatment of the standard parts is mainly to check Whether the anti-corrosion ability of standard parts is effectively increased, and whether the increase is in line with the expected requirements.

1. Application of Industrial Bolt Factory's steel structure bolts
  Steel structure bolts are mainly used for steel structure engineering, and are used to connect the connection points of steel structure steel plates. Steel structural bolts are high-strength bolts and standard components. Better fastening performance, used in steel structure and engineering to achieve the fastening effect. In the general steel structure, the required steel structure bolts are all above 8.8, there are 10.9 and 12.9, which are high-strength steel structure bolts. Sometimes the bolts on the steel structure do not need to be plated.
  Second, steel structure bolt classification
  Steel structure bolts are divided into torsion-shear high-strength bolts and large hexagon high-strength bolts.The large hexagon high-strength bolts belong to the high-strength level of ordinary screws, while the torsion-shear high-strength bolts are improved types of large hexagon high-strength bolts for better construction.
  Three, steel structure bolt construction
The construction of the steel structure bolts must be tightened first and then the final tightening.The initial tightening steel structure bolts need to use impact type electric wrench or torque adjustable electric wrench; while the final tightening steel structure bolts have strict requirements, the final tightening torsion shear type steel structural bolts must Use torsional shear type electric wrench, and the final tightening torque type steel structure bolt must use torque type electric wrench

  Characteristics of steel structure
  Steel structure system has comprehensive advantages such as light weight, factory manufacturing, fast installation, short construction period, good seismic performance, fast investment recovery, less environmental pollution, and high degree of industrialization. Compared with reinforced concrete structure, it has more unique advantages. Globally, especially in developed countries and regions, steel structures are widely used in various engineering constructions, such as steel bridges, steel workshops, steel gates, various large pipeline containers, high-rise buildings and tower rail mechanisms.
  Technical process of steel structure installation
   1. According to the normal installation sequence and process requirements, prefabricating and assembling the steel structure on the steel platform must ensure the quality of welding.
  2. The distance between the splice flange joints of the profiled steel and the splice joints of the web should be greater than 200mm. Flange panel splice length cannot be less than 2 times the width of the plate; web splice width should not be less than 300mm, and the length should not be less than 600mm.
  3. In order to facilitate the welding and ensure the welding quality, as far as possible, the stiffener plates, connecting plates, backing plates, beams, etc. on the pillars, beams, etc. are grouped and welded on the ground steel platform according to the construction drawing size.
  4. In addition to the fabrication and assembly of steel components prefabricated on the steel platform by China Stud Supplier in accordance with the construction drawings and specifications, it is also necessary to consider the changes in on-site installation processability and installation dimensions.

People who often deal with hardware know that fasteners often appear locked during use. Locking fasteners will cause the operation of the fastener itself to be ineffective, that is, it cannot be disassembled or continued to be fastened. Pieces. What causes this to cause the fasteners to lock up? How can I avoid the state of the fasteners locking up? China Stud Supplier - Zhejiang Weigao Standard Parts Co., Ltd. .
　　 1. Reasons for fastener locking
The locking of fasteners generally occurs on products made of stainless steel or alloy materials.This is because these metal materials themselves have the ability to prevent corrosion.Once the metal surface of the fastener is damaged, it will appear to oxidize. Layer to provide protection against the intensification of rust, but when the fastener is locked, the pressure and heat generated by the force will destroy the oxide layer, causing blocking or shearing between the metal threads, and then the phenomenon of adhesion, also It is deadlocked.
　　 2. The method of fasteners to avoid locking:
　　 The locking of the fasteners cannot be completely eliminated, but we can reduce the chance of locking by paying attention to various factors, such as ensuring the load capacity of the fasteners and choosing screws and nuts with more tensile strength.
Whether the thread of the fastener is clean also has a certain effect on whether it locks up.When the thread is rough or unclean, lockup occurs more often, so be sure to clean the fastener and remove iron debris or Dirt.
　　Industrial Bolt Factory's fasteners must be lubricated, but the consequences are very serious. The heat generated by the force on the metal parts will be effectively reduced. This is because it can reduce the locking of the fasteners.

Industrial Bolt does not tighten tightly and keeps slipping. If such a problem occurs, Industrial Bolt Factory can be solved by the following methods:

1. See if the male wire is still slippery, add an aluminum sheet

2. You can flatten the Industrial Bolt. If possible, replace the Industrial Bolt with stainless steel. If it is plastic, it is better to see what material is mainly screwed. For example, if it is wood, add a small wooden strip (toothpick) to the hole. If it is iron

3. Go find some raw material tape, then wrap it around the plastic Industrial Bolt, and then twist it.

4.Industrial Bolt sliding wire can only be changed to Industrial Bolt. If you can’t control it, just cut a little bit of iron in the screw hole and cut it into a long bar. Don’t be too thick and thin (the can can be inside the Wanglaoji). Insert it into the screw hole and screw it. When Industrial Bolt is going to the end, it will slowly twist its own car repair wire. This can be done as long as the force is not too large.
