The Norbar Standard Series HT7 – HT9 Hand Torque Multiplier w/ Anti Wind-Up Ratchet and Adjustable Reaction 1-1/2” Square Drive 16070 is designed for high-torque applications where safety, control, and flexibility are essential. Fitted with an Anti Wind-Up Ratchet, the Norbar Standard Series HT7 – HT9 Hand Torque Multiplier w/ Anti Wind-Up Ratchet and Adjustable Reaction 1-1/2” Square Drive 16070 allow safer and more practical operation by helping contain the forces generated during tightening, improving operator control and reducing the risks associated with stored energy. Their high multiplication ratios enable the use of a small torque wrench as the input tool, reducing operator effort while still achieving substantial output torque in demanding bolting applications.

The HT7HT9 range provides mean torque multiplication accuracy of 4%, supporting reliable, repeatable performance for critical fastening work. The adjustable reaction design gives users greater flexibility to position the reaction point to suit different joint layouts, clearance restrictions, and structural obstructions. For applications requiring tighter process control or monitoring, electronic torque transducers can be fitted to provide more precise torque feedback and improved visibility during tightening. If formal calibration is required, a UKAS accredited calibration certificate may be ordered separately for applications up to 6,000 Nm. Made in the UK, the HT7HT9 series reflects Norbars commitment to durable, precision-engineered torque multiplication tools.

The Norbar Standard Series HT7 – HT9 Hand Torque Multiplier w/ Anti Wind-Up Ratchet and Adjustable Reaction 1-1/2” Square Drive 16070 is ideal for power generation, heavy maintenance, rail, utilities, offshore work, and industrial shutdowns where large fasteners must be tightened accurately and safely. They are especially effective on flanges, structural bolting, and heavy machinery joints where limited access, adjustable reaction positioning, and controlled high-torque operation are critical to safe, efficient performance.
