Product Description
   China made black oxide Stud Bolt astm a193 gr b7
 

     A Threaded Rod, also known as a stud, is a relatively long rod that is threaded on both ends; the thread may extend along the complete length of the rod. They are designed to be used intension. Threaded rod in bar stock form is often called all-thread. Studs may have a drive slot in one end to facilitate installing the stud.For studs that are not completely threaded, 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.
