The adjustable tightening tool is a versatile replacement for sets of spanners, both metric and imperial. The smooth jaws ensure the damage-free installation of plated fittings, while the zero-backlash jaw pressure prevents damage to sensitive components. The tool has parallel jaws for a solid grip and allows infinite adjustment of all widths. Its ratchet principle quickly tightens and releases bolted connections, and the lever transmission is greater than 10:1 for strong gripping power. Made of chrome vanadium electric steel, this slim tool is perfect for tight spaces.
