Screw Thread Design - Fastenal

Screw Thread Design Screw Thread Fundamentals A screw thread is defined as a ridge of uniform section in the form of a helix on either the external or internal surface of a cylinder. Internal threads refer to those on nuts and tapped holes, while external threads are those on bolts, studs, or screws. The thread form is the configuration of the thread in an axial plane; or more simply, it is ...
