A wieldy unidirectional small swing-angle ratcheting wrench devised for torqueing hexagonal nut fasteners axially placed on hydraulic hoses or similar lines. The invention is formed of a pair of facing matching mirror image bident-shaped solid skins bound together through a solid flat filler sandwiched between the handle sections, which also functions as a mechanical support and spacer. The head cavity houses within its U-shaped elliptical head section a wrenching mechanism comprised of an open-ended ratcheting cog wheel with a central hexagonal slot of definite size. The cog wheel is ratcheted by two spring-biased pawls deployed inside the assembled tool's neck cavity which provide continuous alternating unidirectional engagement, while the outer solid skins at the head are suitably shaped to allow protrusion of the cog wheel's teeth at the sides for simple direct rotation of the wheel for alignment of the cog wheel's and skins' openings together for engagement and removal of the tool.
