The Sealey AK624B is a calibrated micrometer torque wrench designed for professional precision tightening applications. This 1/2" square drive tool features a heat treated steel ratchet head that's fully hardened and tempered for long-term durability in workshop and mobile service environments. With a torque range of 27-204Nm (20-150lb.ft), this wrench is ideal for automotive mechanics, plant maintenance engineers and machine assembly work where accurate torque control is essential. The micrometer-type adjustment mechanism provides precise torque setting, with dual scale graduation in both Newton metres and pound-feet for versatility across different specifications. Every wrench is individually tested and supplied with a numbered calibration certificate, with tolerances meeting BS EN ISO 6789-1:2017 requirements. The electrodeposition finish provides corrosion resistance for reliable performance in demanding workshop conditions.
