3 4" Drive Mushroom Head Torque Wrench

The Norbar 3/4" Drive Mushroom Head Torque Wrench is a professional adjustable torque wrench designed for heavy-duty applications requiring precise torque control in the 80-400Nm range. Fitted with Norbar's robust 'Industrial' style ratchet mechanism, this torque wrench delivers exceptional accuracy and reliability for demanding workshop environments. Built around the principle of 'offset pawls', the Industrial ratchet features a 60-tooth pattern with a narrow engagement angle, enabling effective operation even in confined spaces. The reversible square drive can be removed and repositioned to provide torque control in both clockwise and anti-clockwise directions, enhancing the tool's versatility across different fastening applications. Factory calibrated to ±3% accuracy, this professional torque wrench incorporates an advanced mechanism designed to retain precision over extended use. The ergonomic handle features a high proportion of soft-feel, high grip material that resists all chemicals commonly encountered in automotive, industrial and aviation environments. The large scale window and extended scale length ensure clear visibility for accurate torque setting, whilst the secure push/pull locking mechanism prevents accidental adjustment during use. A unique Timestrip® feature provides a visual calibration reminder, helping maintain measurement integrity. Each wrench is supplied with a Calibration Certificate satisfying ISO 6789-2:2017 requirements.
