Norbar 1/2" Drive Mushroom Head Torque Wrench

The Norbar 1/2" Drive Mushroom Head Torque Wrench is a professional-grade adjustable torque wrench designed for precision fastening applications across automotive, industrial and aviation sectors. Factory calibrated to ±3% accuracy, this tool delivers reliable torque control between 40-200Nm, making it ideal for demanding workshop environments where consistent, accurate fastening is essential.

Equipped with Norbar's 'Industrial' style ratchet mechanism, this torque wrench utilises offset pawls to create a robust tooth pattern with a narrow 72-tooth engagement angle. This design enables effective operation in confined spaces where access is restricted. The reversible square drive can be removed and repositioned to provide torque control in both clockwise and anti-clockwise directions, enhancing versatility across different fastening tasks.

The ergonomic handle features a high proportion of soft-feel, high grip material that resists all chemicals commonly encountered in automotive, industrial and aviation applications. A secure push/pull locking mechanism prevents accidental adjustment during use, whilst the large scale window and extended scale length ensure excellent visibility for precise torque setting. The unique Timestrip® feature provides a visual indication when re-calibration is due, supporting ongoing accuracy and compliance.

Supplied with a Calibration Certificate to satisfy the requirements of ISO 6789-2:2017, this torque wrench is suitable for professional tradespeople and contractors requiring traceable, certified accuracy for quality assurance systems.
