  Unannounced visit to shoulder screw manufacturers Sometimes we will want to know the real situation of the factory, right? Generally, we will inform others of the specific time when we visit. But this may be deceived,someone don’t like this. It’s like an orange that looks delicious. But you don’t know if it is so sweet when it is in your mouth, or it may be sour. We have also encountered customers who came to visit without notifying us in advance. Of course, our  shoulder  screw manufacturers  are welcome! He is a purchasing manager from Dongguan, operating electronics. They need screws, so we all have the intention to cooperate. But his boss wants to wait until he visits the factory before deciding.So he came to our factory secretly. Then we took him to visit our production workshop. He wondered how  shoulder  screw manufacturers  could do so well. The person in charge of the shoulder screw manufacturer said, because we have this strength and c...

Shi Shi Tong Screw Factory specializes in producing all kinds of non-standard shoulder screws. Among the various non-standard shoulder screws, the slotted shoulder screw is the most commonly used and seen by us. So, do you know the  slotted   shoulder screw ? Metric  slotted shoulder screw  can also be called shoulder bolts. What is a shoulder screw? A fastener with a non-threaded cylindrical section between the thread and the screw can be called a shoulder screw. The diameter of the shoulder is greater than the diameter of the thread and provides a shaft to fit around the tightly fitting moving parts. The slotted shoulder screw can be matched with the shoulder part below, and the diameter of the shoulder can be as small as the small diameter of the thread. The slotted shoulder screw is determined by the diameter and length of the shoulder. Of course, the shoulder screw can also produce a hexagon socket. The dimensional tolerances of the shoulde...

When designing a new product, we usually need screws to fasten our products. How do we determine the  shoulder screw dimensions metric  when determining the step screws used on the product? The determination of the  shoulder screw dimensions metric  is not that easy. Sometimes the size is not reasonable, then this screw can not be formed. Or the difficulty is too high, many manufacturers can not produce, it takes a lot of time to find a manufacturer that can produce this screw. There is a very simple way to determine the  shoulder screw dimensions metric . According to the standard step screw size, there will be no problem that the screw structure is unreasonable, or the manufacturer cannot be found. Or take a sample of the product and find a screw manufacturer. Basically, the screw manufacturer will give advice on how to design the screw to avoid the problem of the structure of the screw.

Stainless steel shoulder screw  are not a standard screw fastener, and many customers are concerned about the price of this screw. Shenzhen Shi shi tong production screw manufacturers for your analysis. First, we need to know all the dimensions of this stainless steel shoulder screw before calculating the price of the stainless steel shoulder screws. The size is different, the weight is different, and the price is different. In general, the larger the size of the step screw, the more expensive the price. Second, you need to know the surface treatment of this stainless steel shoulder screw. For example, one is to electrophoresis, and a direct color cleaning can be shipped. The price of electrophoresis is calculated as one grain and one grain. The color cleaning is generally calculated in kilograms. If the weight does not meet the requirements of the electroplating factory, then the charge is calculated according to their minimum weight. Finally, there is another quant...

The  shoulder screw  tolerance is also standard. What is the difference between the tolerance of the shoulder screw tolerance of the ordinary screw? Let’s first understand what a tolerance is. Tolerance is the allowable variation in the actual parameter values of a machine or machine part in the design and manufacture of the machine. The shoulder screw tolerance are similar to those of ordinary screws if the requirements are not as strict. For mechanical manufacturing, the purpose of setting tolerances is to determine the geometric parameters of the product so that the variation is within a certain range in order to meet the requirements of interchange or fit. Important and critical dimensions are marked with dimensional tolerances on the mechanical drawings. Other dimensions are generally indicated in the “Technical Requirements” column. If there is no specification in the “Technical Requirements”, the (IT13) tolerance is taken. Shoulder screw tol...

What is a shoulder screw ? Now the  Shoulder Screw manufacturer – SHI SHI TONG METAL   will answer for you. Shoulder screws, also known as shoulder bolts and stripper bolts, are machine screws with an integral shoulder or journal between the head and thread. … In these applications, they are commonly called stripper bolts . Shoulder screws are simply understood as a non-standard screw with two or more steps. This kind of shoulder screw, usually do not have in stock, it is to need to open mold to produce .   Screws Type:  Shoulder Screws Shoulder Screws Diameter :  M2-M16 Shoulder Screws  Length :   3-200mm Surface Treatment Blue and white zinc, color zinc, black zinc, nickel plating, copper plating, black and various environmental protection plating . t is a shoulder screw? SHI SHI TONG METAL adopt new high precision imported fastener equipment and international leading production technology. Production and sales of national...

The shoulder  screw  is simply a non-standard screw with two or more steps. Shoulder screw , also known as shoulder bolt, or clamping bolt, It are used in a wide range of precision gaskets and bearings. The scapula is uniquely identifiable by the long, cylindrical, middle (shoulder), which is wider than the threaded portion but narrower than the head. When screwed into the surface, the stepped portion remains above the aperture, allowing rotation of accessory components such as pulleys, gears, mechanical components, and rolling wheels. They can also be used to attach stripping plates to secure high torque in a limited clearance environment. The general shoulder screw  are not in stock and need to be opened for custom production.  Shenzhen Shi  S hi  T ong Screw Factory uses all-professional fastener production machines, high-quality wire and 20 years of experience in production, sales and sales of standard and non-standard shoulder screw . The fasten...

When many customers ask for the screw, they will ask if there is any way to improve the corrosion resistance of the screw. Today, Shi Shi Tong  Screw Factory will tell you that this method can improve the corrosion resistance of ultra low profile shoulder screw  by 10%. Can't wait to know what is the way to improve the corrosion resistance of ultra low profile shoulder screw  by 10%? There are several ways to improve the corrosion resistance of the ultra low profile  screws. First, we can prevent the screws from being corroded from the environment in which the screws are used, that is, the screws are assembled in an environment that would corrode the screws. However, this is more difficult to achieve, especially when used in a special environment; the second method is to select a corrosion-resistant material on the material of the selection screw. For example, the corrosion resistance of titanium is very strong, as the budget allo...
