The Sealey STW706 is a professional-grade 3/4" drive micrometer torque wrench engineered for heavy-duty applications requiring precise torque control. Built from hardened and tempered Chrome Vanadium steel with a polished satin finish, this robust tool delivers reliable performance across an extensive torque range of 150-800Nm (111-590lb.ft), making it ideal for commercial vehicle maintenance, heavy plant equipment servicing, and industrial assembly applications. The smooth-action ratchet head features a flip reverse mechanism, enabling accurate torquing in both clockwise and anti-clockwise directions. This bidirectional capability proves particularly valuable when working in confined spaces or with left-hand threaded fasteners common on certain machinery. The micrometer adjustment system allows precise torque setting with a secure locking mechanism to maintain your selected value throughout the job. Calibrated to BS EN ISO 6789-1:2017 standards, each wrench undergoes individual testing to achieve ±4% accuracy and comes with a numbered test certificate for traceability and compliance purposes. The dual-scale graduation in both Newton metres and pound-feet eliminates conversion errors when following manufacturer specifications. At 1230mm long, this substantial tool provides the leverage needed for high-torque applications whilst maintaining control and accuracy.
