The Loosening Of Blind Rivet Nut
In our lives, we often see or hear about various accidents. Among the many accident cases, there is often a seemingly inconspicuous cause, that is, loose screws. A small blind rivet nut can cause great harm.
In long-term work practice and life, it is found that small locknuts often cause huge troubles due to automatic loosening. Due to mechanical vibration and other reasons, the originally tightened screws will gradually become loose, so they must be... see more reinforced frequently to prevent loosening of the threads. The difference with self-locking thread will waste a lot of human resources in the reinforcement process. At present, preventing the screw from loosening has become a worldwide problem.
Normal nuts will loosen due to vibration and other reasons during use, such as vibration. To prevent this phenomenon, self-tightening nuts were invented. The main function of the self-tightening nut is anti-loose and anti-vibration. For special occasions. Its working principle is generally self-tightening by friction. The types of self-tightening nuts classified according to their functions are those with embedded nylon rings, those with neck closures, and those with metal anti-loosening devices. They are all effective torque-type locknuts.

Introduce Thread Rolling Of Hex Rivet Nut
There are many applications of nuts, so we can see nuts in many places. The hex rivet nut is usually hexagonal, and the inner hole is an internal thread, which is used to cooperate with the bolt and tighten the related parts. Today we talk about thread rolling of hex rivet nut.
The forming rolling die for thread rolling plastically deforms the workpiece to obtain the self-tapping screw thread. The processing method of self-tapping screw thread... see more rolling is generally performed on a thread rolling machine or an automatic lathe with an automatic opening and closing thread rolling head. It is suitable for the mass production of external threads of standard fasteners and other threaded couplings.
The outer diameter of the rolled thread is generally not more than 25 mm, and the length is not more than 100 mm. The thread accuracy can reach level 2 (GB197-63). The diameter of the blank used is roughly the same as the pitch diameter of the thread being processed. Rolling generally cannot process internal threads, but for softer workpieces, non-slot extrusion taps can be used to cold extrude internal threads (the maximum diameter can reach about 30 mm). The working principle is similar to tapping. When cold-extruding internal threads, the required torque is about twice as large as tapping, and the machining accuracy and surface quality are slightly higher than tapping.

Flat Head Rivet Nut And Countersunk Rivet Nut
We all know that in our daily life we can often see all kinds of rivet nuts, one of which is flat head rivet nut. The daily use of flat head rivet nut is also quite extensive.
A flat head rivet nut is a kind of nut in metrology. The rivet nuts sold in the market can be classified into flat head rivet nuts and countersunk head rivet nuts according to the head type. The most common is the flat head rivet nut.
From the perspective of... see more use, the fastening effect of flat head rivet nuts is better, and this type of rivet nut is generally used. However, some places require the surface to be flat after riveting, so a counterbore can be made in the process and then riveted with a countersunk rivet nut, so that after the riveting is completed, the riveted surface is flat. But the mechanical properties of the countersunk head will be lower than that of the flat head rivet nut.
In addition to these two rivet nuts, carbon steel rivet nut is also very good in terms of performance. www.khfastener.com

Manual And Electric Use Of Hex Rivet Nut
Nuts, nails, and other confinement tools are used to install many things around us. The hex rivet nut is a kind of rivet nut that we can often see.
Riveting nuts are used in real life. Because the specifications are different, the purpose is also different. And many people know this tool, but don’t know how to use it correctly. There are manual and electric tools for rivet nuts. Nowadays, there are still very few manual applications. To improve... see more work efficiency, they will choose to use electric rivet nuts.
The method of using tools for rivet nuts is different, especially now that many people widely use electricity, because the manual method is relatively backward, and the efficiency is also very low. Electricity can make up for this shortcoming, and at the same time, it can be very effective. Solve practical problems quickly, greatly improve the efficiency of time and work. It is indeed 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.
Therefore, you must pay attention to your safety when using nuts such as the half hex rivet nut . www.khfastener.com

Understand The Specifications Of Half Hex Rivet Nut
Both hex rivet nut and half hex rivet nut are novel and practical sheet metal fastener products. The deformation of the rivet nut is similar to the bulging deformation process of cylindrical parts or pipe materials. Generally, the bulging coefficient is used to indicate the degree of bulging deformation.
The current specifications of rivet nuts are M3, M4, M5, M6, M8, M10, M12. It is recommended to use M6 and M8 rivet nuts. Small thread... see more blind rivet nuts can be directly tapped on the plate and bolts when using large threads. The weight is increased, the riveting force of the rivet nut is limited, and the matching is not reasonable enough. Rivet nuts are widely used on aluminum alloy substrates with different thicknesses and steel plates with a thickness of 1-2.5mm. The connection of steel rivet nuts in aluminum alloy components eliminates the cumbersome and manufacturability of embedding steel plates inside. Significant improvement.
Half hex rivet nut and hex rivet nut is widely used in the connection of board parts in various industries such as shipbuilding, vehicles, aviation, electrical appliances, meters, metal cabinets, elevators, etc. The operation is simple, the connection is reliable, beautiful, low-consumption, and high-efficiency. www.khfastener.com

Misunderstanding Of The Use Of Blind Rivet Nut
We can see many types of fasteners in our daily lives, and blind rivet nut is also a kind of fasteners. So what are the misunderstandings in the use of blind rivet nut?
There are impurities such as rust, scale, iron filings, sand particles in the threads of bolts, nuts, or screw holes, or there are impurities such as burrs, mud, and sand on the joint surface of the coupling parts, which have not been removed before assembly. When tightening... see more the bolts, due to impurities The blocking effect is that the surface is tightened very tightly, and the torque value meets the requirements, but in fact, the coupling is not compressed; also, there is another situation, due to the supporting effect of impurities such as sludge and scale in the screw hole, Although the bolt torque complies with the regulations, the workpiece is not tightened. Under such false solidity, vibration, load shock, and temperature changes often cause the bolts to loosen quickly.
The above is a misunderstanding of using blind rivet nut false solid snails. Of course, countersunk head rivet nut will also have misunderstandings. www.khfastener.com

The Material Used By Hex Rivet Nut
If we need to use a nut on a thin iron sheet, because the iron sheet is too thin, it is not easy to tap and weld. At this time, we need to use a blind rivet nut or a pressure rivet nut. We all know that the hex rivet nut and other rivet nuts are widely used in the sheet metal industry. Rivet nuts are often used in our home life.
The hex rivet nut is made of galvanized iron, 304 stainless steel, and 316 stainless steel. The specifications supplied are... see more M3-M12. The hex rivet nut is divided into flat head hexagonal blind rivet nuts and small head hexagonal blind rivet nuts, which are installed in the hexagonal bottom hole. Because of its hexagonal shape, it can completely prevent slippage and can withstand greater torque. After testing, even if the thread is damaged, the hexagonal rivet nut can still be firmly riveted on the thin plate. Its installation method is the same as that of ordinary circular riveting. The installation method of the nut is the same, except that when punching the bottom hole, it must be punched into a hexagonal hole that is compatible with it. The national standard number is GB/T17880.5.
The shape of the half hex rivet nut is slightly different from that of the hex rivet nut, and the purpose and installation method are very similar. www.khfastener.com
