2. ISO metric screw thread - Wikipedia

   en.wikipedia.org/wiki/ISO_metric_screw_thread

   A metric ISO screw thread is designated by the letter M followed by the value of the nominal diameter D (the maximum thread diameter) and the pitch P, both expressed in millimetres and separated by a dash or sometimes the multiplication sign, × (e.g. M8-1.25 or M8×1.25). If the pitch is the normally used "coarse" pitch listed in ISO 261 or ...

3. Screw thread - Wikipedia

   en.wikipedia.org/wiki/Screw_thread

   A screw thread is a helical structure used to convert between rotational and linear movement or force. A screw thread is a ridge wrapped around a cylinder or cone in the form of a helix, with the former being called a straight thread and the latter called a tapered thread. A screw thread is the essential feature of the screw as a simple machine ...

4. Unified Thread Standard - Wikipedia

   en.wikipedia.org/wiki/Unified_Thread_Standard

   It is the main standard for bolts, nuts, and a wide variety of other threaded fasteners used in these countries. It has the same 60° profile as the ISO metric screw thread, but the characteristic dimensions of each UTS thread (outer diameter and pitch) were chosen as an inch fraction rather than a millimeter value.

5. Nut (hardware) - Wikipedia

   en.wikipedia.org/wiki/Nut_(hardware)

   Nut (hardware) An M4 nut threaded onto an Allen key socket head screw. A nut is a type of fastener with a threaded hole. Nuts are almost always used in conjunction with a mating bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction (with slight elastic deformation ), a slight ...

6. Preferred metric sizes - Wikipedia

   en.wikipedia.org/wiki/Preferred_metric_sizes

   For each size bolt or screw and type of head, there is a corresponding size driver prescribed by various ISO standards, including: Internal hex drive: ISO 2936:2014 "Assembly tools for screws and nuts—Hexagon socket screw keys" External hex drive: ISO 4014, 4016, 4017, and 4018

7. Screw - Wikipedia

   en.wikipedia.org/wiki/Screw

   Metric hexagon bolts, screws and nuts are specified, for example, in International Standards ISO 4014, ISO 4017, and ISO 4032. The following table lists the relationship given in these standards between the thread size and the maximum width across the hexagonal flats (wrench size):
