- Misunderstanding Of Using Blind Rivet Nut
There are many places where we use rivet nuts, so there is a great possibility that blind rivet nut will be used, but we will have some mistakes when using blind rivet nuts. Let's take a look at two of them.
The washer of the screw and nut is too large: Sometimes because of the lack of a suitable washer, some people use a washer with a larger inner diameter instead. In this way, the contact area under the head of the bolt with the washer is small, the bearing pressure or locking force of the washer is reduced, and the bolt is easy to loosen under the action of vibration and impact load.
The torque of the screw and nut are inconsistent: Many people think that the screw and nut should be "tighter than loose", so they consciously increase the tightening torque of the screw and nut, resulting in the screw and nut sliding buckle. On the other hand, it is important for the need to tighten with torque. Some people try to save trouble and use an adjustable wrench to tighten the screws and nuts. As a result, they often loosen due to insufficient torque, leading to mechanical failure.
In addition to blind rivet nut, countersunk head rivet nut is also the same, you should pay attention to some misunderstandings when using it.www.khfastener.com0 0 Comments 0 Shares
- The Electric Rivet Nut Aluminium
Aluminum rivet nuts are used in real life, because the specifications are different, the purpose is also different, and many people know this tool, but do not know how to use it correctly. In fact, there are manual and electric tools for rivet nut aluminium . Nowadays, there are very few manual applications. In order to improve work efficiency, electric rivet nuts are chosen.
Riveting products provide great convenience for the unilateral connection of thin plate parts. It can complete fast and effective connection without bulky installation tools and can generate stable standard internal and external threads. It can be installed after surface treatment by cold work without pollution. An effective alternative to welding nuts. Main applications: automobile-body, seat belt system, bumper, seat belt system, bumper, airbag system, etc. . Unidirectional plate connection 2. Produces standard internal and external threads 3. Conventional product range: M3-M12 4. Material: carbon steel, stainless steel, aluminum 5. High-quality pneumatic tools-Efficient, economical, lightweight, and simple to operate. The principle used is still the same as the manual rivet nut.
The method of using tools for stainless steel rivet nut is different, especially now that many people widely use electric, because the manual method is relatively backward, and the efficiency is very low. Electricity can make up for this shortcoming and at the same time. Solving practical problems quickly, greatly improving the efficiency of time and work, it is indeed very widely used, but you must pay attention to the method when using it. If you do not follow the correct method, it is easy to harm your body.www.khfastener.com0 0 Comments 0 Shares
- Stainless Steel Rivet Nuts Are Shrinkage
We all know that there are many rivet nuts we can access and there are many types of rivet nuts, and the probability that we can use rivet nuts is also very high. Whether in industry or at home, we have direct access to rivet nuts. Although it is small, its function and value are great. And there are many types of stainless steel rivet nuts, such as hexagonal stainless steel rivet nuts, hexagonal stainless steel rivet nuts and so on. Since there are so many types and values of stainless steel rivet nut , do you know stainless steel rivet nuts?
Since the stainless steel rivet nut is deformed under the condition of axial pressure applied at its two ends, the force is better than the bulging shape in which the radial pressure is applied to the simple shape or the pipe material. After riveting, the length of the stainless steel rivet nut will be shortened, and its shrinkage is related to its material plasticity and size. In order to prevent the bulging coefficient from exceeding the allowable value and causing cracks in the bulging, the shrinkage must be controlled.
Stainless steel rivet nuts are mainly used in non-structural bearing bolt connections, such as the connection of interior parts such as rail passenger cars, highway buses, and boats. The improved rivet nuts that can prevent spin are more excellent than the pallet nuts for aircraft. It is lighter in weight, no need to fix the pallet nut in advance with rivets, and the back of the substrate can still be used without operating space.
Whether it is rivet nut aluminium or stainless steel rivet nuts, it is the same. We must pay attention to this problem during use, so no matter how small it is, we need to treat it well.www.khfastener.com0 0 Comments 0 Shares
- Large Countersunk Head Rivet Nut And Small Countersunk Head Rivet Nut
We still see and use rivet nuts in our daily lives, so how much do you know about rivet nuts? The purpose of the rivet nut: If the nut of the product needs to be installed outside and the internal space is small, the indenter of the sub-rivet machine cannot enter the rivet, and the sprouting method cannot meet the requirements. If the strength is required, riveting and expansion riveting are not feasible. Blind riveting must be used. Suitable for the fastening field of plates and tubes (0.5MM-6MM) of various thicknesses. It can be riveted by pneumatic or manual rivet gun at one time, which is convenient and firm. Instead of traditional welding nuts, it can make up for the shortcomings of thin metal plates, thin tubes, easy welding, and non-smooth welding nuts. In addition, there are many types of rivet nuts, one of which is called countersunk head rivet nut .
The countersunk head rivet nut is called "the gospel of the thin plate connection process" abroad. It changes the old method of traditional craftsmanship. When installing parts on a thin plate, there is no need to knock internal threads and weld nuts. Strong, beautiful and convenient. , Fast function, can be widely used in the assembly of electrical and light industrial products such as *, aviation, railways, refrigeration, elevators, switches, instruments, furniture, decorations, etc.
The countersunk head rivet nut is riveted into the chamfered thin plate hole, and its top surface is flush with the plate surface after installation. As the name suggests, the outer diameter and thickness of the head of the small countersunk head rivet nut is smaller than the (large) countersunk head rivet nut. If the metal plate is relatively thin and the chamfer is small, only small countersunk head rivet nuts can be used.
Therefore, the use of countersunk head rivet nuts is still very much.www.khfastener.com0 0 Comments 0 Shares
- Material Classification Of Carbon Steel Rivet Nuts
Rivet nuts are one of the most used materials in hardware materials. They usually appear in various metallic materials. They are mainly used for fastening materials, but they also solve the problem that the base material is prone to welding deformation over time and solve the problem of internal ribs caused by slippery teeth defects. When the material is locked, it is very fixed and easy to use and store. It is one of the most important hardware materials for production and industrial use, carbon steel rivet nut is one of them. .
At present, the standard rivet nuts on the market mainly include carbon steel, stainless steel and other materials.
The first is carbon steel. We distinguish low carbon steel, medium carbon steel, high carbon steel and alloy steel according to the carbon content of carbon steel materials.
1. Low carbon steel C%≤0.25% is usually called A3 steel in China. It is basically called 1008, 1015, 1018, 1022, etc. abroad. Mainly used for products that do not require hardness, such as grade 4.8 bolts and grade 4 nuts, small screws. (Note: 1022 material is mainly used for drill tail nails.)
2. Medium carbon steel 0.25% 3. High carbon steel C%> 0.45%. Basically not used in the market.
3. Alloy steel: Add alloying elements to ordinary carbon steel to increase some of the special properties of steel: such as 35, 40 chromium molybdenum, SCM435, 10B38. Fangsheng screws mainly use SCM435 chromium-molybdenum alloy steel, the main components are C, Si, Mn, P, S, Cr, Mo.
The second type is stainless steel. Performance grade: mainly divided into austenite (18%Cr, 8%Ni), with good heat resistance, good corrosion resistance and good weldability. A1, precision hardware, A2, A4 martensite, 13% Cr, poor corrosion resistance, high strength, moderate price, and good wear resistance. C1, C2, C4 ferritic stainless steel. 18% Cr has better creep resistance and corrosion resistance than martensite. Currently, the imported materials on the market are mainly Japanese products. According to the grade, it is mainly divided into SUS302, SUS304 and SUS316.
Both flat head rivet nut s and carbon steel rivet nuts are rivet nuts, which are good choices in terms of appearance and function. As long as there is industry on the earth, the function of fasteners will always be important.www.khfastener.com
