We often encounter customers who claim to have screws made in the American system, even though they are in the British system. What is the difference between the two before?
Firstly, due to the fact that both British and American screws are expressed in inches and most specifications have the same pitch, people mistakenly believe that they are the same. In fact, most specifications can indeed be matched.
There are also differences in the standards between the two, as there are differences in data such as screw heads.
The difference between British screws and American screws is difficult to distinguish visually. The difference between British and American screws is that the rubbing angle of British screws is 55 degrees, while that of American screws is 60 degrees,
Therefore, from the perspective of the diagram and the thread, we can see that there is actually a significant difference between the two, so they must be used correctly and not mixed. During the assembly process, it is necessary to understand whether the threads are in the British or American system. If the customer cannot determine, they can send samples to our company, and we will use thread gauges and projections to assist the customer in determining the specifications of the threads.
