Screwclamped

Screwclamped is an adjective used in manufacturing, woodworking, and prototyping to describe a workpiece or fixture that is held in place by a screw clamp during processing. The term emphasizes the method of restraint—via a screw mechanism—rather than a fixed joint or permanent fastening.

Common screw clamps include C-clamps, bar clamps, and screw vises. In practice, a screwclamped setup uses a threaded shaft or screw that applies pressure to tighten a jaw against the workpiece. The clamping force can be adjusted gradually, enabling precise alignment and repeatable positioning for milling, drilling, gluing, or inspection. Screwclamped arrangements are reversible and often chosen for temporary holding before permanent fastening or finishing.

Advantages and considerations: Screwclamped workpieces allow adjustable, repeatable pressure with relatively simple tooling; they minimize permanent alteration to the workpiece and are suitable for delicate or composite materials. Limitations include potential surface marring from jaws, time required to tighten for precision, and the need to ensure parallelism and edge alignment. For higher-volume production, alternative clamping strategies or integrated fixtures may be preferred.
