ABSTRACT
Romanian special standards - according to international (ISO) ones - show metric threads of common use for this kind of screw elements (bolts, nuts); there are a lot of standardized and un-standardized variants and also for any mechanical threaded pieces. In usual practice, the threads are executed with normal (standard) pitch. Other cases, when fine pitch in choose, there are some functional behaviour, besides all the dimensional particularities. All these cases, the screw-on torque are significantly diminished given the situation of standard pitch use. The paper delivers here a theoretical analyze of functional thread characteristics and also brings some other lucrative results for mechanical design practice.
