  How to distinguish the material of long screw? Sometimes when we look at the  long screw , is not to see the material of the screw, especially the screw surface treatment, it is difficult to distinguish in the end is iron material or stainless steel, other material is better to distinguish, so how to distinguish its material? By weight, copper > stainless steel > iron > aluminum > pure titanium. The density of stainless steel material is about the same as that of iron material. The  long screw  under the same specification has no difference in weight. But if it’s very light, it’s basically titanium and aluminum. Stainless steel with iron material  long screw , can distinguish through the magnet, but sometimes stainless steel material screw specification is relatively small, may contain some weak magnetic, will cause the screw will also be magnet to suck. This time can be distinguished by the stainless steel potion. If the titanium and aluminum scre...

  What effect does the die line of 304 stainless steel long screw have? Regarding the production of  304  stainless steel long screw , the Shi Shi Tong screw manufacturers are generally used to produce the mold closing machine, there will be a thin mold closing line under the screw head produced by the mold closing machine, will there be any impact on the assembly of this mold closing line? Many customers worry that the clamping line under the  304  stainless steel long screw  head will affect the assembly. If the customer requires that there is no gap between the item and the diameter of the screw when it is assembled, and it needs to be very flat. Then the clamping line under the screw head may affect the assembly. If the clamping line affects the assembly, the clamping line needs to be removed. However, some customers will worry about this closing line is not to fall. In fact, this clamping line can be removed. When the head of the screw and the rod...

  Is long screw an advantage of screw manufacturer? Screw do know that the types of screws are many, which must have sold good products and not too good products. What is the advantage of selling a good product? Why are the products that don’t sell well? Whether a product sells well or not is determined by many factors. According to statistics, the long screw is the advantage of  screw manufacturer  shi shi tong products, let’s have a look together, why this product sells well? First, the length. The length of the decision to the customer, the customer said, we can make as long as the screw. The longer the length, the higher the requirement for hardness. That as a  screw manufacturer , will certainly first understand the purpose of the customer to buy screws to recommend the appropriate hardness, this is no doubt.   Second, quality and technical withdrawal. A French customer once contacted us to make a 5-meter long screw. In fact, the customer has already bought...

In common screw production, it is to make a head-first commonly, rub tooth again. Then the  extra long stainless machine screws  are also produced in this way?   Generally, when the length of the screw is more than 100mm, the material is stainless steel, thread type is machine thread, can be called  extra long stainless machine screws . Their mode of production is different from the usual cold heading of screws. Because the length of the screw is too long, there is not so long spare space in the machine for cutting. So they need a separate cutting machine to do the cutting. After the completion of cutting, then the cut material into the debugging of the good closing machine to start. If the screw is a cup head hexagon, then it can only make the cup head shape, the hexagon shape is not hit, need to make the cup head shape, then take the hole, after drilling the hole, then the hexagon shapes out. The reason why the cup head hexagon socket extra long stainless steel mac...

Now, the concept of customization has entered the minds of many people. Even screw fasteners can be customized. Then, the head size of   long brass machine screws  can be customized? The head size of long brass machine screw cannot be customized at will. Why is this?   The following may occur if the head size of the  long brass machine screws  is customizable. One is that if the screw is made cold heading, the head of the screw may not line up. This is because materials have different coefficients of expansion for forming screws, and the machine also has requirements for the range of molding. Therefore, if the size of the head is set too large and too thin, it may not be able to form. The second is to consider the problem of   long brass machine screws  in actual use. Sometimes, there will be a screw turned, the head broke. One is because of the material, the other is because of the design of R Angle under the head, too small will cause the screw head ...

When ordering the  long thin screw , the customer cooperates with the manufacturer, and most people believe that it is fate. However, Shi Shi Tong screw manufacturers believe that fate is also ready to come. Otherwise why are so many screw manufacturers, customers will find you? Mr. Zhang’s company has developed a new product that requires a number of the  long thin screw  to assemble. Mr. Zhang’s found a lot of screw manufacturers on the Internet for inquiry. After carefully comparing a number of screw manufacturers, and to the screw manufacturers closer to him to field visits, finally, Mr. Zhang chose the Shi Shi Tong screw manufacturers to produce slender screws.

With the development of the Internet, when we shop now, we often buy it online. When we find a manufacturer that can produce long screw  on the Internet, we generally shop around and then choose a screw manufacturer with a lower price. Most friends who choose a low price will think that they are cheaper and save a sum of money. But is this the case? First of all, the threshold of a screw manufacturer is not very high. With a few machines, the screws can be processed. Although the production of long screws is not so easy, it can also be produced by welding. The long screw  produced in this way is not the same quality for the long screws produced by the cold head clamping. And the price is different. The quality of the long screws produced by the mold clamping is much better than that produced by welding. In addition, the price of long screw  is low, and sometimes it is related to raw materials. For example, a screw manufacturer uses an authen...

Today, Shi Shi Tong screw manufacturers have introduced a new die spotting  extra long screw . But a screw length 56 cm? Isn’t that more than half a meter long? Yes, the picture above is the short screw that our die spotting machine made. Shi Shi Tong screw manufacturers can be infinitely  extra long screw  according to customer needs, and of course there are no customers who require unlimited length. The Shi Shi Tong screw manufacturer gave us a 1.2 meter  extra long screw  for training. Because the camera technology needs to be improved, it will be displayed next time.

At present, the cold rolling process used by Shi Shi Tong screw manufacturers to produce long screws is one-time cold forming of...

What type of screw is the  5 inch long screws ? If you still don’t know, please see the picture below. But today I want to talk about screw thread knowledge. The 5-inch in the  5 inch long screws  is an inch size. In China, the metric size is used to express the size of the screw. Inch screw threads are also divided into Imperial Coarse Teeth (UNC) and Imperial Fine Teeth (UNF). BSPT and BSP are dimensional dimensions of the inch size, and of course the NPT American size dimension thread, which is the U.S. standard thread for general use, and NPTLUOWEN is used in the ANSI specification. PT Japanese standard dimension thread, etc., but PT thread is an inch thread, used in Europe and the United Kingdom federal countries, of course, China’s Taiwan and Japan JIS standards are also used in British standards. The number in front of the inch size represents one inch or 25.4 mm, and the  5 inch long screws  is a 127 mm long s...

Although there are many screw manufacturers in China, not all screw manufacturers can find  really long screws  of 100mm. Even if you find a manufacturer that can produce long screws, after using it for a while, you will find that the head of the long screw is disconnected from the rod. So, how do we find a long screw manufacturer that you can rest assured? When purchasing  really long screws , we will look for suppliers or manufacturers. What should we ask at the beginning of the production process they use? How did you make the long screws? The production process of long screws is nothing more than these: one is formed by welding. That is, the head and the rod are separately formed, and the head and the rod are connected by welding. There is also a cold shovel that is molded at one time using a clamping machine. This production method allows the head and the stem to be formed at one time, reducing the risk of breakage. Of course, there is another one that is proc...

Shi Shi Tong screw manufacturers have received orders for many long screws in the past year, and there are many orders for  m5 long screw . Once a customer came to our factory to see our long screws, asked us why these M5 screws are basically half-threaded? And the length of the thread is not long, is there anything to pay attention to? The reason why these  m5 long screw  are semi-threaded, is mainly produced according to the needs. And if the thread of the M5 long screw is full thread, it takes a lot of time to screw it in. Therefore, the customer also wants to save time in this part, so he made a half thread. The thread length of the  m5 long screw  also determines the cost of the screw on the one hand, not necessarily the longer the length of the thread. And if the thread length is too long (for example, more than 100mm), Shi Shi Tong can’t do it. Because the range of the Caspian screw manufacturers’ boring machine is within 100mm. If yo...
