WebbThe major diameter is a critical dimension to control. Together with the pitch diameter, it forms the addendum of the thread and controls if the screw would fit on a bolt. The … For a screw, this is its outside diameter (OD). The major diameter of a nut cannot be directly measured (as it is obstructed by the threads themselves) but it may be tested with go/no-go gauges. The major diameter of external threads is normally smaller than the major diameter of the internal threads, if the threads are … Visa mer A screw thread, often shortened to 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 … Visa mer Screw threads have several applications: • Fastening: • Gear reduction via worm drives • Moving objects linearly by converting rotary motion to linear motion, as in the leadscrew of a jack.
