Types of Threaded Bar
Full bodied or undercut?
All-thread Studding/ Bar/ Rod/ Chemical Anchor has a thread along the whole length of a cylindrically formed material.
There are two types of studs: full-bodied studs, and undercut studs. Full-bodied studs have a shank equal to the major diameter of the thread. Undercut studs have a shank equal to the pitch diameter of the screw thread. Undercut studs are designed to better distribute axial stresses. In a full-bodied stud the stresses are greater in the threads than in the shank.
Undercut studs (rolled thread) are also stronger because the metal is "rolled" up to the major diameter, not removed/ cut away/ wasted. This preserves the grain of the steel, and in some cases even enhances it. Full bodied studs (cut thread) are weaker because metal is removed to create the thread, disturbing the grain of the steel.
Undercut studs are only required in applications where the stud is exposed to fatigue. Cut threads are entirely suitable for many applications, even when rolled threads might be slightly stronger. Mass-produced fasteners (standard bolts and studs) are usually rolled, but jobbed parts with custom features can be cut on request.
