High-torque fastening in industrial maintenance, fleet workshops and remote service environments can be difficult when a standard torque wrench cannot deliver the required output. The Norbar HandTorque HT3-1000 increases the torque applied through a compatible wrench, providing a practical manual solution for applications requiring up to 1,000 N·m.

The multiplier uses multi-stage epicyclic gearing to convert a lower input torque into a higher output torque. Its nominal multiplication ratio is 5:1, but the actual ratio depends on the reaction configuration: 4.8:1 with the cranked reaction foot and 4.9:1 with the straight reaction. Use the applicable ratio when calculating the required input torque.

The listed working range is 100–1,000 N·m. The unit accepts a 1/2" square drive torque wrench and drives a 3/4" square drive socket. Its quick-change cranked reaction can be positioned in eight orientations, helping users adapt the setup to different working conditions. The multiplier weighs approximately 2.7 kg.

With no external power source required, the HT3-1000 is suitable for workshops, offshore facilities, remote industrial sites and field maintenance operations where powered equipment may be impractical or restricted. It is supplied with both cranked and straight reaction bar styles for greater setup flexibility.

For applications requiring greater output torque, compare the Norbar HandTorque HT3 1300 N·m kit and select the model that best matches your fasteners and available torque wrench.

Who This Product Is Best For

  • Industrial workshops handling 3/4" drive fasteners up to 1,000 N·m.

  • Fleet and equipment maintenance teams requiring portable torque multiplication.

  • Offshore, oil and gas and petrochemical facilities where powered tools may be restricted.

  • Field technicians working in remote locations or areas with limited access.

  • Workshops that already own a compatible torque wrench and need greater output torque.

How to Specify & Install It

  1. Confirm the required output torque: Ensure the application falls within the listed 100–1,000 N·m range.

  2. Check drive compatibility: Verify that your torque wrench has a compatible 1/2" square drive and that the output socket suits the 3/4" square drive.

  3. Select the reaction arrangement: Choose the cranked or straight reaction according to the application and the manufacturer's instructions.

  4. Identify the correct ratio: Use 4.8:1 for the cranked reaction or 4.9:1 for the straight reaction when calculating input torque.

  5. Calculate the input torque: Divide the target output torque by the applicable multiplication ratio.

  6. Fit the tool securely: Connect the torque wrench and socket, then position the reaction component against a suitable, solid reaction point.

  7. Apply torque smoothly: Follow the manufacturer's operating procedure, keeping hands clear of reaction and pinch points. Do not exceed the rated limits of the multiplier, wrench or socket.

  8. Inspect after use: Check the tool and reaction components for visible damage and store them appropriately.

Frequently Asked Questions

It delivers up to 1,000 N·m, with a listed working range of 100–1,000 N·m.

2. What is the torque multiplication ratio?

The nominal ratio is 5:1. The stated ratio is 4.8:1 with the cranked reaction and 4.9:1 with the straight reaction. Use the ratio corresponding to the selected setup.

3. How accurate is the HT3-1000?

Its specified torque multiplication accuracy is better than ±4%. This refers to the multiplier's performance and is separate from the accuracy of the torque wrench used to drive it.

4. What are the input and output drive sizes?

The HT3-1000 uses a 1/2" square drive input and a 3/4" square drive output.

5. What reaction components are supplied?

The unit is supplied with cranked and straight reaction bar styles. The cranked reaction can be positioned in eight orientations.

6. Does the HT3-1000 require an external power source?

No. It is manually operated and requires no electricity, batteries or compressed air.

7. How does it compare with the HT3 1300 N·m kit?

The HT3-1000 has a listed maximum output of 1,000 N·m, while the HT3 1300 kit reaches 1,300 N·m. Choose according to the required output torque, drive sizes and compatible torque wrench.
