Part of that is probably because we’ve gotten so good at making them that they’re seen as cheap commodities, but the physics and engineering behind the screw thread is interesting stuff.

Screw Thread Forms. Of the various screw thread forms which have been developed, the most used are those having symmetrical sides inclined at equal angles with a vertical center line through the ...

The principal parameters determine the basic functional properties of the screw thread, such as whether it can be assembled with a mating part, whereas the complementary parameters affect the service ...
