  What should I pay attention to for half-thread self-tapping stainless steel screws? For screws, the thread type of the screw is divided into machine thread and self-tapping thread. There are full thread and half thread in the self-tapping thread. So what should be paid attention to when ordering half-thread  self-tapping stainless steel screws ? If the customer says that he wants to order half-thread  self-tapping stainless steel screws , then he needs to know the length of the thread and the diameter of the rod (the part without threads under the head). Especially the diameter of the rod must be known because the size of this place will affect whether the screw needs to be opened. When the diameter of the shaft of the half-thread self-tapping stainless steel screw is too small, the screw manufacturer must also consider whether the size of the head can meet the customer’s requirements and whether it can be expanded using this size of the wire. If the material does not e...

  How to install steel self tapping screw? Generally, when we need to install two accessories, we usually need screws to tighten them. It may be a machine screw or it may be a steel self-tapping screw. Then how to install  steel self tapping screw ? Some people say that there is no need to punch holes in the installed parts in advance when installing  steel self tapping screw s, just take the screws and attack them directly. Some people also say that it is necessary to punch holes in the installed parts in advance so that it will be better when fastening. In fact, both ways can be done. If the fitting is not punched in advance, then the  steel self tapping screw  may appear during the installation and be a little crooked when tapped, or the electric screwdriver may not be used, so little effort will be spent in the screw and it cannot be screwed in. If holes are punched in the installed parts in advance, we can tighten the parts quickly when screws are used for ...

  stainless steel special screws are produced by what machine?

  Why can titanium screw break a head? Screws are generally used as accessories to fasten things, mobile phones, computers, mouse, etc. Above the figure of screws can be seen. But sometimes, when we use, we find that the screws are broken, such as  titanium screw , why do they break? There is not only one reason for  titanium screw  to break. There are many factors that can cause screws to break. If you can see a groove mark where the screw is broken, it is because the groove is too deep that the screw is broken. In such a case, the screw manufacturer should pay attention to the depth of the groove of the screw during production, and need to make the depth of the groove smaller in the next production. If you don’t see grooves in the area where the break is, then there’s probably too much torque during use. No matter what type of product, there is a fixed torque value, when the torque is exceeded, the product will be broken. The same is true of titanium screws. You ne...

  Can stainless steel flat socket cap screw be made into machine wire with pointed tail? Mr. Xu’s company developed a new product some time ago, so it needed to order a new screw.

  How to distinguish the material of long screw? Sometimes when we look at the  long screw , is not to see the material of the screw, especially the screw surface treatment, it is difficult to distinguish in the end is iron material or stainless steel, other material is better to distinguish, so how to distinguish its material? By weight, copper > stainless steel > iron > aluminum > pure titanium. The density of stainless steel material is about the same as that of iron material. The  long screw  under the same specification has no difference in weight. But if it’s very light, it’s basically titanium and aluminum. Stainless steel with iron material  long screw , can distinguish through the magnet, but sometimes stainless steel material screw specification is relatively small, may contain some weak magnetic, will cause the screw will also be magnet to suck. This time can be distinguished by the stainless steel potion. If the titanium and aluminum scre...

  What do I need to pay attention to when I electroplate pure titanium screws? The reason why the screws to do electroplating is to look good, the other is to increase the corrosion resistance of the screw. But if you do not pay attention to electroplating, it will cause the screw can not be used. So what should I pay attention to when I electroplate  pure  titanium screws ? One is the coating thickness. Sometimes if the coating on the  pure  titanium screws  is too thick, the screws cannot be screwed in. Because nuts or internal threads are made according to the standard thread tolerance, if the screw coating is too thick, it will cause the outside diameter of the thread to become larger, beyond the standard thread tolerance range, it will not be able to be used to tighten objects. Two are plating surfaces. Generally, the surface of screws is required to be free from defects. Titanium screws are fine if they are used inside and not exposed. However, if the...
