Representation of nuts
Thread Content
How are the nuts used for connection at both ends of a metal flexible hose indicated? For example, in the case of a DN40 metal bellows, the connection nuts at both ends are M48*2. What does 48 represent, and what does 2 represent? Additionally, there is a metal tube with DN32 specification, and the measured distance between the opposite sides of the connection nuts at its ends is 38. What size should be chosen for such nuts? Seeking advice, urgent need
48 is the thread diameter, 2 is the pitch
They are bolts used to connect the two ends of the flexible metal hose, and they need to be relatively large in size
