Nelson Metric MPF studs have a short unthreaded weld base, so that, after welding, the usable threads essentially extend down to the weld metal. They are used for fastening applications on heavy gauge base materials where development of the full fastener strength is needed. The short unthreaded section minimizes the weld flash diameter and height. It also reduces the possibility of stud hang up in the ferrule cavity if gun parts are slightly misaligned. Ferrules with a special low profile and large diameter are sued to weld MPF style studs. Nelson partially threaded studs have a pitch diameter weld base and are available in thread diameters of M6 through M16 with unlimited length. Nelson MPF studs conform to AWS D1.1, TS16949, and ISO 9000:2000.
