DEF

A ridge of uniform section in the form of a helix on the external or internal surface of a cylinder, or in the form of a conical spiral on the external or internal surface of a cone or frustum of a cone.

CONT

Continuous helical ribs on a cylindrical shank. Screw threads are used principally for fastening, adjusting, and transmitting power.... A thread on the outside of a cylinder or cone is an external(male) thread; a thread on the inside of a member is an internal(female) thread.

OBS

The screw thread is used either to ensure an assemblage or to transmit motion.

Subject field(s)
  • Joining Elements (Mechanical Components)
CONT

"screw threads" : Continuous helical ribs on a cylindrical shank.... If a single helical groove is cut or formed on a cylinder, it is called a single-thread screw. Should the helix angle be increased sufficiently for a second thread to be cut between the grooves of the first thread, a double thread will be formed on the screw. Double, triple, and even quadruple threads are used whenever a rapid advance is desired, as on fountain pens and valves. The helices on a double thread start 180 ° apart, while those on a triple begin 120 ° apart.
