Continuous Thread Studs Type 1 Type 2 Continuous-thread studs are threaded from end to end and are often used for flange bolting with two nuts applied. Type 1 - General purpose. The length of this type is measured from end to end. These studs are made to the dimensional standard requirements of ANS B16.5 and have a length measurement requirement different from all other studs, i.e., the length is measured from first thread to first thread, exclusive points.
Points are flat and chamfered.
Threads are UNRC-2A for all sizes 1 in. This end is for screwing into a tapped hole. The other or nut end is threaded with a Class UNRC-2A fit. Length of the stud is measured overall. The tap end has a chamfered point, but the nut end may have either a chamfered or round point, at the manufacturer's option.
