feed mechanism of machine tools
screw cutting lathes
A bolt of M 24 × 2 means that
the pitch of the thread is 24 mm and depth is 2 mm
the cross-sectional area of the threads is 24 mm2
the nominal diameter of bolt is 24 mm and the pitch is 2 mm
the effective diameter of the bolt is 24 mm and there are two threads per cm

decreasing its shank diameter
tightening the bolt properly
making the shank diameter equal to the core diameter of the thread
A bolt of uniform strength can be developed by
keeping the core diameter of threads equal to the diameter of unthreaded portion of the bolt
keeping the core diameter of threads smaller than the diameter of unthreaded portion of the bolt
keeping the nominal diameter of threads equal to the diameter of unthreaded portion of bolt
none of the above
