  Button head self tapping screws process The production of  button head self tapping screws  has always required a standard process. Don’t look at the size of the screws, but the screwing process must not be underestimated. The screws are small, and the process can be produced quite a lot! Through the screw, the factory sees the screwing process. How is the screw made? In fact, from the process, I believe you will have a clearer understanding. The  button head self tapping screws  production process mainly includes seven steps of annealing, pickling, drawing, forming, caulking, heat treatment, and surface treatment. Annealing is mainly to heat the wire to a suitable temperature for a certain period of time, and then slowly cool to adjust the crystal, reduce the hardness, and improve the normal temperature processability of the wire. Pickling is designed to remove the oxide film on the surface of the wire and form a phosphate film on the metal surface to reduce ...

  Can miniature self tapping screws be delivered within 10 working days? Mr. Jin wants  miniature self tapping screws  of M1.4, but Mr. Jin did not find them in stock on the Internet, and there is no spot in the same size. In desperation, Mr. Jin can only find manufacturers to produce. However, Mr. Jin found several screw manufacturers.

Later, some individuals and Mr. Jin recommended the Shi Shi Tong screw manufacturers, saying that they can make small screws for M1, let Mr. Jin ask.   So Mr. Jin contacted Miss Song of Shi Shi Tong screw manufacturer and asked Miss Song if there is a spot of M1.4  miniature self tapping screws . If there is no spot, how long does it take to produce? Miss Song asked Mr. Jin about the size of the screw. Mr. Jin gave us the drawings and asked us to give him a price accordin...

  It is worthy of being a friend to recommend the countersunk self tapping screws manufacturer reliable Mrs. Mi of Zhongshan went to her friends once to work, talking about the durability of the  countersunk self   tapping screws  used in her factory, which led to the continuous increase in the cost of purchasing. After knowing the situation, her friends tried her best to recommend SST to Mrs. Mi, so later Mrs. Mi became naturally connected to the SST countersunk self-tapping screw manufacturer. Because Mrs. Mi is to do auto parts, so the precision and hardness of  countersunk self   tapping screws  are more strict, only after high frequency heat treatment countersunk head tapping screw can reach the hardness required by meter small, in terms of accuracy is also very difficult to process, only imported precision equipment plus experienced old master can achieve such strict accuracy requirements.

  Titanium screws manufacturer, 21 years screw supplier Shenzhen Shi Shi Tong Metal Products Co., Ltd. can produce Gr1 Gr2 pure titanium screws. The  titanium screws   manufacturer   has 21 years of production experience and has been researching and producing various difficult non-standard screws for a long time. Titanium screws are the same as ordinary stainless steel, iron, and copper screws, except that they are made of titanium. The titanium material is pure titanium TA1 TA2. Alloy titanium is sometimes used. Titanium screw raw materials are more expensive, and they are also very beautiful. It seems that crafts and titanium are resistant to acid and alkali corrosion, so the price of titanium screws is generally higher. Generally, titanium screws are used on relatively high-end products and can be used on teapots, household appliances, and military machinery, and aircraft. Therefore, the use of titanium screws is also very extensive, because of their better perfor...

  Hardware Screw Suppliers – Take each sample sheet seriously!   When a company wants to find hardware  screw supplier s  to customize the screws, be sure to polish your eyes. If you choose some technologies but are not responsible for the small factory, then you will definitely not find the same screw supplier. Screws, this is also human nature. In fact, many companies have chosen to buy a lot of hardware suppliers, but they don’t know. The small hardware screw suppliers are simply looking at the drawings and then making quotations. They have not communicated carefully with customers. I think I am professional, ignoring the actual use of screw fasteners, a large part of the hardware screws made, can not meet the needs of actual use. When a company develops new products, which hardware  screw supplier s  to choose is the key to whether your design and development effects can reach their limits. There is a supplier of such hardware screws in Shenzhen, they p...

  This small self tapping screws manufacturer thinks about the problem from the customer’s point of view. Since the  small self tapping screws  are frequently used parts, sometimes the screws may have quality problems such as rust and breakage and need to be replaced. But if you change it often, you have to think about the problem. Mr. Mu of Shenzhen has encountered such problems. Mr. Mu needs to use  small self tapping screws  from time to time. Recently, the small self-tapping screws purchased by Mr. Mu frequently have quality problems. The screws assembled are less than one month, and the screws on the top are basically rusted. Mr. Mu will re-purchase a small number of small self-tapping screws, which will also lead to an increase in Mr. Mu’s procurement costs. Therefore, Mr. Mu was very experienced in the screwing of the Shi Shi Tong screw manufacturer. He consulted the Shi Shi Tong screw manufacturer and also brought the assembled products and the...

  According to the production of countersunk self tapping screws samples June 10, 2019, the  countersunk self tapping screws  manufacturer Shi Shi Tong Metal Products Co., Ltd. received samples from Australia. It is a black countersunk hexagon self-tapping screw. From the appearance, there is no difference from our common  countersunk self tapping screws . We tested the customer’s sample data and found that this was a UNC countersunk self-tapping screw rather than a metric countersunk screw in China. As the customer said it was easy to slide and break the head. We tested the strength of the screw, and found that the sample sent from the customer was not subjected to hardening heat treatment After we asked about the customer’s request for strength, the final customer decided to add a hard to 6.8 grade. The pre-load torque corresponding to the 6.8 level was 674.3-732.7N and the received torque was 0.23-0.28 Nm. June 16, these  countersunk self tapping screws ...

  Why is the binding head tapping screw easy to break? Some customers bought the  binding head tapping screw  and used them back. They found that the screws are always easy to break. Why is this? The  binding head tapping screw  is easy to break, there are several reasons: ——The torque is too large. Use the torque of this screw to tighten the screw, so the screw will break. ——In addition to hydrogen is not complete. When the binding head tapping screws are made of carbon steel, the hydrogen is not completely removed, and it will be brittle when used, which is what we call hydrogen embrittlement. ——Not the strength level we require. For example, we require a 12.9-stage  binding head tapping screw , but in fact, it is a 10.9-class screw. When we use it, we use the corresponding torque of 12.9 to use the screw, and the screw will also break. ——The thread bottom diameter is too small. No matter what the screw, there is a thread bottom diameter. And the thread b...
