Thread Rolling Screw HWH Slot (Bulk Carton)
A thread rolling screw has a continuous helical set of threads formed on a body. The threads have a tip section, an intermediate section, and a final section. In the tip and intermediate sections, the diameters of the crests progressively increase. In the intermediate section, relieved areas are spaced apart around the crests of the threads. In the final section, the threads are continuous and circular and of constant diameter. The crest of the last intermediate thread is the same diameter as the crests of the final thread section.
