5.2.3. Max length of threaded rod
Threaded rods are commonly used for suspension and fixing pipe clamps/brackets. Important to keep in mind is that threaded rods
are designed to be used in tension and not typical for bending forces, therefore the length of the threaded rods have predefined
maximum lengths. The total maximum length of the threaded rod depends on the strength class. If the strength class is unknown,
the lowest strength class of 4.6 should be used. If the strength class is known, the maximum length of the threaded rod can be
retrieved from table 22.
