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 ...

POWER SCREWS (ACME THREAD) DESIGN. There are at least three types of power screw threads: the square thread, the Acme thread, and the buttress thread. Of these, the square and buttress threads are the most efficient. That is, they require the least torque to move a given load along the screw. However, the Acme thread is not greatly less efficient, and it is easier to .
The stress in the screw when the screw has been tightened to the design extent is known as the prestress. The tensile load corresponds to the force that clamps the joint members together. External loads which are less than the clamping force will not change the tensile load in the screw. On the other hand, if the joint is exposed to higher external loads than the prestress in the bolt the ...

the screw. A handbook on the design and operation of Archimedes screws (Nagel 1968, p. 37) states that, based on field experience, the rotational velocity of a screw in revolutions per minute should be no larger than 50/D2/3, where D is the diameter of the outer cylinder in meters. Thus a screw with an outside diameter of 1 m should have a maximum rotational velocity of 50 rpm. If .
