  What are the causes of stainless steel cap screws fracture? Generally,  stainless stee l cap  screws   are not easy to fracture. So under what circumstances does it cut off? Here are four common situations below. First, the raw materials used for making screws have quality problems. Stainless steel screw wire quality is not good, there are a lot of impurities inside, will lead hardness of stainless steel screw is not enough. Second, the customer exerts too much force when using  stainless steel cap screws . Normally can do torque test,clear their own breaking force, and then adjust the torque.   Third, the process of producing  stainless steel  cap  screws .  For example, stainless steel screws with eccentric head, or Q value is too deep and R site design is too small in the case of manufacture work. Fourth, clear whether the pre-drilling is appropriate or not. If the pre-drilling is too small, the screw w...

The third method: the screw can be directly knocked off with an electric pulse. So the question is, how do the  socket hex c...

Mr. Mao’s company is close to Shi Shi Tong and it takes only 13 minutes to drive. Mr. Mao’s company recently needed a  stainless metric socket head cap screws , M5*495mm long. Mr. Mao knew that we could produce his screw and came to our factory. When Mr. Mao looked at the samples of the long screws we had produced, she took a long screw and asked if the thin wire under the head of the  stainless metric socket head cap screws  was a production error. Looking at the position pointed by Mr. Mao, we told Mr. Mao that this was not a production mistake. Because this screw is molded at one time through the mold clamping machine. At the time of molding, there will be a mold line, which is this small line. But this thin line does not affect the use. Just ask Mr. Mao to accept this thin line? Mr. Mao said that he can accept this thin line, and then Mr. Mao asked us how his  stainless metric socket head cap screws  is made. Can you let him see it...

Mr. Hong’s customer needs a  hexalobular socket head cap screws  and gave Mr. Hong’s drawings to Mr. Hong to help him purchase this screw. However, Mr. Hong has never touched the screw industry before, nor does he know whether the dimensions marked on the drawings are reasonable. Therefore, he began to find a screw manufacturer that can produce this screw. Occasionally, Mr. Hong found Shi Shi Tong and gave us the drawings of his customer’s  hexalobular socket head cap screws . After reviewing the drawings given by Mr. Hong, we suggested with Mr. Hong that the model of the torx should not be so large. When the edge is easily broken and cannot be used, let Mr. Hong change the model of the torx. . Mr. Hong said that he looked at the inside of the drawings and the size of the torx was still inside the head. He thought that what type of torx could be used, only the size of the torx blossoms did not exceed the size of the head. Then Mr. Hong said that he woul...

For some screw fasteners used in some products, the required performance is different. Some require  metric allen head cap screws  to have anti-rust ability, and some hexagonal screws need anti-theft performance, corrosion resistance and so on. If we need hex screws with anti-rust properties, how should we choose? The anti-rust ability of the  metric allen head cap screws  mainly comes from the material characteristics of the screw itself and the surface treatment of the screw. Generally, the screw material with anti-rust ability is generally made of stainless steel, and the 304, 316 stainless steel grade screw fastener is used more, secondly, titanium material. The screw fasteners also have high rust and corrosion resistance, but the price is high. In addition to the material of the screw, the  metric allen head cap screws  has the ability to prevent rust, and the surface treatment is also very important. The stainless steel screw can be passivated fo...

Screw fasteners are inseparable from our lives. As long as it is a mechanical device, there are basically screw fasteners on it, and it is difficult to find the screw fastener on it. When we use screw fasteners, they are generally used together with matching nuts, gaskets, and the like. But when we used stainless steel screws, we found that the  stainless button head cap screws  were locked up after a while. Why is this? There are several reasons that may cause this to happen: one is the 304HC material used for stainless button head cap screws, and the nut material used is also 304HC, which will lock up. The second is that during the tightening process, the force is uneven or inclined. The third is that when the tightening is too strong or the speed is too fast, the friction caused by the stainless steel screws becomes soft and the adhesion occurs. Fourth, when assembling, the screws that are screwed in are not perpendicular to the threaded holes. Shi shi tong scre...

And there are still some wires left for us to produce. Therefore, it takes about 5 days for the  aluminum button head cap screws  to be shipped. Mr. Shen said that the delivery date was faster than he ex...
