  Why is the thread diameter of #6-32 stainless steel Phillips screws different? Among our commonly used screw thread diameters, there are M3, M4, M5, etc., these with “M” in front of them refer to metric threads. In addition to metric threads, there are imperial threads in fasteners, such as #6-32, this means that the thread diameter is #6, and “32” means that there are so many threads in one inch. But if you have measured a lot of #6-32  stainless steel  Phillips  screws , you will find that their thread diameters are somewhat different. Why is this? If it is a standard #6-32  stainless steel  Phillips  screws , their thread diameter range is 3.33mm-3.48mm, this is UNC coarse thread, and the thread angle is the thread size of 60°. At the same time, this thread size also means that the screw is produced according to the 2A tolerance code. In addition to the tolerance code of 2A, #6-32 also has a tolerance code of 3A, and their thread diameter is 3.35m...

  How to install steel self tapping screw? Generally, when we need to install two accessories, we usually need screws to tighten them.

  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...

  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.
