Part No. HT-2/25 AWUR (3/4" out)
The Norbar HT-2/25 AWUR is designed for applications requiring high output torque with a 3/4" drive socket. Its multi-stage epicyclic gearbox converts input torque from a compatible torque wrench into a much higher output, making it suitable for industrial maintenance, assembly and heavy bolting work.
The nominal multiplication ratio is 25:1, and the listed working range is 170–1,700 N·m. Norbar specifies the true torque multiplication ratio, so confirm the exact mean torque ratio before calculating input settings for critical joints.
This listing specifies a 1/2" square-drive input and a 3/4" square-drive output. The anti-wind-up ratchet helps control stored energy in the gear train and reduces the risk of the input wrench kicking back when released. As the standard HT-2/25 AWUR is listed with a 1" output, confirm the exact part number and 3/4" output configuration with General Tech Services LLC before ordering.

Frequently Asked Questions
What is the maximum output torque of the HT-2/25 AWUR (3/4" output)?
It delivers up to 1,700 N·m, with a listed working range of 170–1,700 N·m.
What is the multiplication ratio?
The nominal torque multiplication ratio is 25:1. Confirm the exact mean torque ratio before setting input torque for critical joints.
How accurate is this Norbar HandTorque multiplier?
Its stated torque multiplication accuracy is better than ±4%.
What does AWUR mean?
AWUR stands for anti-wind-up ratchet. It helps control stored energy in the gearbox and reduces the risk of the input wrench kicking back when released.
What are the input and output drive sizes?
This listing specifies a 1/2" square input and a 3/4" square output. Confirm the exact output configuration before ordering.
Should I choose the 3/4" or 1" output version?
Choose the output drive that matches your socket requirements. The standard HT-2/25 AWUR is listed with a 1" output, so contact General Tech Services LLC to verify the availability and part number of the 3/4" version.
