When ordering the screw fasteners, many customers will ask for the torque of the screws, especially when it is made of carbon steel. So what is the   torque specifications for machine screws ? When the   torque specifications for machine screws  of the screw does not meet the requirements of the customer, the screw of the screw will be easily broken when the customer uses the screw of the screw, and the screw cannot be used. Different screw specifications, the torque of the screw is also different. For the corresponding screw specifications, refer to the table below. Therefore, when you do not know the   torque specifications for machine screws , you can view this table, and use the tool to test the torque of the screw to meet the requirements.

Mr. Cai received an order from a customer some time ago. Several  socket head countersunk screw dimensions  of different lengths were used. The customer only gave CAD of Mr. Cai’s assembly products, and did not give drawings of Mr. Cai’s screws. Therefore, he is not sure what the size of the Hexagon countersunk head screw is. Mr. Cai wanted to find a screw manufacturer to determine his screw size. After that, Mr. Cai found a screw manufacturer closer to him and went to the screw factory in person. Because Mr. Cai did not have the actual product in life, only the CAD drawing of the product, the CAD drawing of this product was given to the screw manufacturer, I want him to help confirm the  socket head countersunk screw dimensions . On the same day, Mr. Cai confirmed the size of the rubber-resistant countersunk head screws with the screw manufacturer and paid them to them for production. But when Mr. Cai received the screws and took them to the assembly, they f...

There are many types of screw fasteners, and depending on the product, the types of screws are different. So what are the   different types of screws and their uses ? Precision small screws, generally used in precision instruments, electronic products, watches, mobile phones, etc. The precision small screws can be divided into many types depending on the material, size, groove shape, head shape, and tooth type. The precision small screw has only a rough name. The shoulder screw mainly refers to a step or more than one step under the head, which is called a step screw. This type of screw is generally non-standard, depending on the user’s product, the step size, thread diameter, length, and head size of the screw are also different. Generally used in industries such as machinery and electronics. Long screws or extension screws. This type of screw is mainly because the length is much longer than the conventional screw. Such long screws are generally used on lighting...

Mr. Chang wants a  stainless steel flat head machine screws , but his head shape is not a conventional countersunk shape. On the Internet, he could not find the spot with the shape of the countersunk head he wanted. In desperation, Mr. Chang found Shi Shi Tong. According to the drawings provided by Mr. Chang, we found that Mr. Chang’s  stainless steel flat head machine screws  is similar, but the size of the screws is not the same, the shape is the same. I found out the stainless steel countersunk head screw that we had done before, and took it to Mr. Chang to see that we had done similar before. Mr. Chang’s screw can also be done. However, we did not reach a cooperation with Mr. Chang later. Although Mr. Chang knows that we can do  stainless steel flat head machine screws , Mr. Chang chooses a screw manufacturer close to him to let them produce. Because Mr. Chang’s delivery time is too late, if we remove the transportation time, we can reach Mr. C...

Once, Shi Shi Tong screw manufacturers received a call from a customer saying that he needed an M4 countersunk head screw and asked us what the price was. Then we asked the customer what the  m4 countersunk machine screws dimensions  is. Is there any drawing? The customer said that he did not have drawings and asked us, is the size of the M4 countersunk head screw not the same? In fact, the  m4 countersunk machine screws dimensions  is not the same. Different screw types, even if they are M4 size, are one of the step screws, one is a regular or standard screw, and the other is a long screw, and their dimensions are different. M 4 countersunk machine screws dimensions  is generally composed of length, head diameter, head thickness, and groove size. The diameter and thickness of the head are mainly determined by the angle of the countersunk head, while the angle of the countersunk head is generally 90°, 80°, and 100°. Therefore, the size of the ...

Mr. Ben needs a M3.5 extra long socket screws 100mm . He doesn’t know where to find the manufacturer that produces this screw. I don’t know if M3.5 can be made so long. The longest length he has ever used is M3.5*75. When Mr. Ben first started, he went to the factory that supplied him with M3.5*75 screws. Can he do  extra long socket screws 100mm ? The screw manufacturer told Mr. Ben that they couldn’t do that long. Later, Mr. Ben saw a picture on the Internet, the screws inside the picture are very long. Then Mr. Ben clicked in, so Mr. Ben found the Shi Shi Tong screw manufacturer. We told Mr. Ben that we can make M3.5  extra long socket screws 100mm  and ask what material is Mr. Ben’s screws. Mr. Ben said it is made of pure titanium. Can you do it? Shi Shi Tong screw manufacturers of countersunk materials can also be done. Then Mr. Ben asked us to quote him a price. After reporting the price to Mr. Ben, he accepted our price. And let us make a formal cont...

Screws in excess of 100mm and grooved hexagonal socket screws are collectively referred to as  long screws for plug sockets . Screws over 100mm are generally half-threaded and do not require full threads, which only increase the cost and difficulty of production. The diameter of the  long screws for plug sockets  is divided into big rod and small rod. If the rod diameter is larger than the thread diameter, this is the long screw of the big rod, need to open die production, the cost increases. If the diameter of the rod is less than the diameter of the thread, this is the long screw of the small rod, and the diameter of the rod is the diameter of the wire, which reduces the weight of the screw, reduces the die and reduces the cost. So how do I choose a big shank diameter or a small shank diameter with a  long screws for plug sockets ? According to your own products, we suggest that we should ch...
