  What is the material used for the grade 8 self tapping screws? The  grade 8 self tapping screws  are depending on what material used for the supplier. If it is common low-carbon steel material, the strength grade of the grade 8 self tapping screws will not meet grade 8, and the maximum of 6.8 self-tapping screws can be achieved. In the Shi Shi Tong, the material of the medium carbon steel 10B21 or the high-carbon steel SCM 435 can be chosen, and after the hard heat treatment, the strength grade is determined to be 8 or even higher grade. Grade 8 self tapping screws , the standard should be grade 8.8 self tapping screws, meaning that the tensile strength of the tapping screw is 800Mpa, and the yield strength is 800×0.8=640Mpa. In order to achieve 8 grade self-tapping screws, the most basic one should also choose 10B21 medium carbon steel material. Some factories choose carbon steel 1018, the surface hardness can reach 8 grades, but the core hardness can not meet the requ...

  How to measure micro self tapping screws? The size of the  micro self tapping screws  is relatively small and quiet, and there is often a problem of insufficient torque during use. So how do you test the torque of a small self-tapping screw? We can use the torque tester to measure the tightening force of the screw and the twisting force of the screw to determine how much the  micro self tapping screws  can be twisted. This instrument is often used in screw companies. Bureau of measurement, etc. A torque tester is mainly used to tighten screws, break screws, twist screws, test screw torque, etc. The screw tester has a unique external design, simple operation, complete functions, suitable for general tightening, inspection and rupture test, convenient hand-held, direct reading, large dial for easy reading. Its characteristics are: rapid measurement saves time; can reduce defective products; assess roundness error; easy to operate and versatile; light and easy to...

  Screw manufacturers always have a way to produce the products you need The products manufactured by Shi Shi Tong  screw manufacturers  are always based on the needs of customers. In many cases, we must constantly improve the technology to meet the requirements of customers. At the same time, we also develop a standard for our technical processing. excitation. In continuous improvement, our technology is constantly being provided, and the two grow together. Now a product that Shi Shi Tong  screw manufacturers  are producing is custom-made for a US customer, Allen. This customer doesn’t know much about screws, so send their products to us and let us design dimensional drawings for him. After we sent the drawings to the customer confirmation, the customer said, “I think this size is very suitable for our products.” So without hesitation, the customer quickly placed the order. Customers are still not assured before mass production, and samples must be produced fir...

  Steel tapping screws manufacturers according to your needs production S teel tapping screws  are general-purpose materials for the general industry, and different screws are produced according to the requirements of use. The application of steel tapping screws is very extensive, and the usage of various industries is also very wide. Many times we usually say that the iron material is carbon steel, and the cast iron and carbon steel are both iron and carbon alloys. The fundamental difference between cast iron self-tapping screws and  steel tapping screws  is the carbon content. What is the difference between them? The carbon content is 2.08% (some with a boundary of 2.11%) or more, and the following is steel. However, in practical applications, it is generally called wrought iron or pure iron with a carbon content of less than 0.03%, and the content is 0.1-1.7%. Steel is divided into low carbon steel according to carbon content (C ≤ 0.25%); medium carbon steel ...

  Production of various materials from self tapping screw supplier For some people who do not like to waste time on finding products, they prefer to buy all the things they need in the same place, so many people like to go to the supermarket shopping. The purchase of screws is the same. For customers who need many different materials, it is also convenient to find a  self tapping screw supplier  that can produce many different materials. Stainless steel, carbon steel these two materials a lot of screw manufacturers will produce. But copper, aluminum, titanium material, compared to the first 2 materials, can produce the manufacturer is not so much. Because of copper, aluminum, titanium material wire than the two materials, not so easy to order. Shi Shi Tong  self tapping screw supplier , is able to produce stainless steel, carbon steel, copper, titanium, aluminum screws. Shi Shi Tong  self tapping screw supplier  can not only produce these 5 materials, but a...

  Why is the stainless steel self tapping screws easy to break? In the current fast-growing economic environment, no matter which industry, the competition is very intense. The same is true for the screw industry. Inside the screw, why is the  stainless steel self tapping screws  easy to break? The weight of the  stainless steel self tapping screws  is important both at the time of the quotation and at the time of transportation. With a little less weight, the cost of the product will drop a little, and many times customers are choosing suppliers and paying attention to cost. Therefore, at the time of production, some screw manufacturers will choose to make the bottom diameter of the screw small, so that the thread diameter of the  stainless steel self tapping screws  produced is within the tolerance range, and the weight of the screw will also be reduced. However, the screw that is produced in this way has a bad point and is easy to break. Since the s...
