U Bolts Grip and Non Grip Type (1/2″)M15 – (24″)M600

Stud bolts known as studs are categorized into 3 basic types: Tap End Stud Bolts, Fully Threaded Stud Bolts,  and Double End Stud Bolts. Each of these has different engineering applications. Tap end studs have threads at extreme ends of the stud having unequal thread length, but double end stud bolts are differed in that they have equal thread length at both ends. Fully threaded studs are threaded fully across the body for full engagement of the matings nuts or similar parts. Apart from these, there are stud bolts for flanges which are fully threaded studs with chamfered ends, and double end studs with reduced shank for special bolting applications. If it’s studded that are not completely threaded you’re looking for, there are two types of studs to look at full-bodied studs, and undercut studs. Let’s look at Full-bodied studs, they have a shank equal to the major diameter of the thread. Now undercut studs are slightly different and have a shank equal to the pitch diameter of the screw thread. These undercut studs are designed to better distribute axial stresses. Full-bodied studs have stresses that are greater in the threads than in the shank.
