screwadjusted

Screwadjusted is an adjective used to describe a device, mechanism, or system in which adjustment is achieved via screw-based elements, typically through threaded fasteners or micrometer screws, enabling incremental changes in position, tension, or alignment.

In mechanical design and manufacturing, screwadjusted components include panel-mounted clamps, linear slides with adjustment screws, and joints that use set screws to tune fit. In optics and photography, screws with fine travel allow precise calibration of focus, tilt, or alignment. In furniture and fixtures, screw-adjusted leveling feet or feet with leveling screws support stable operation on uneven floors.

Advantages include precision, repeatability, and compact integration; adjustments can be made without disassembly. Drawbacks include slower tuning compared with lever or pneumatic systems, potential backlash or wear in threads, and the need for periodic tightening to prevent drift.

Origin and usage: the term is a compound formed from screw and adjust and appears in maker and engineering discourse in the 2010s and 2020s as a descriptive label rather than a standardized technical term.
