Worm gear

A cylindrical worm gear shown in side view or slight three-quarter perspective as a short, thick screw-like shaft of uniform diameter. The body is metallic steel-gray with a smooth machined, slightly polished finish. A single continuous deep helical thread wraps evenly around the entire outer surface, forming coarse, pronounced spiral ridges with rounded grooves and a clear crest-and-root thread profile. The ends are plain, smooth, and shaft-like with rounded or simple extensions, and the central rotational axis is visible at the ends. The overall form resembles a compact power-screw gear element designed to mesh with a worm wheel, without flutes or cutting edges.
