The Knipex 86 03 Series plier wrench combines the functions of pliers and a wrench into a single tool, eliminating the need for multiple sets of metric and imperial spanners. It features smooth, parallel jaws that remain consistently aligned, ensuring damage-free installation of plated fittings and allowing for direct work on chrome surfaces. This tool is ideal for applications involving plated radiators, shower fittings, or tap fittings, and it is designed not to damage soft materials during normal use. The zero-backlash jaw pressure prevents damage to the edges of sensitive components, making it particularly suitable for precision mechanics and work on small bolted connections.
