Screwtype
Screwtype is a broad, nontechnical term used to describe components and mechanisms that rely on a helical screw thread to convert rotation into linear motion or to hold components together. It is not a single formal category, but it covers fasteners, linear actuators, some pumps, and certain power-transmission devices that use screw action.
Fastening applications: The most common screwtype components are threaded fasteners such as screws and bolts. They
Motion and actuation: In machine tools and automation, lead screws or power screws provide controlled linear
Rotary screw devices: The term screwtype also covers fluid machinery such as rotary screw pumps and compressors,
Design considerations: When selecting screwtype components, engineers evaluate load capacity, travel length, backlash, wear, lubrication, and
