The 16089.HD Norbar Standard Series HT1 – HT6 Hand Torque Multiplier with Anti Wind-Up Ratchet and Sliding Reaction, 1” Square Drive is engineered to provide high-output torque with greater control, safety, and adaptability. Fitted with an Anti Wind-Up Ratchet, the 16089.HD Norbar Standard Series HT1 – HT6 Hand Torque Multiplier with Anti Wind-Up Ratchet and Sliding Reaction, 1” Square Drive offers safer and more practical operation by helping manage the stored forces generated during tightening. This improves operator confidence and control, especially in high-torque applications where conventional hand tools would be difficult or unsafe to use. Their high multiplication ratios allow a small torque wrench to be used as the input tool, reducing operator effort while still achieving substantial output torque.

With mean torque multiplication accuracy of 4%, the 16089.HD Norbar Standard Series HT1 – HT6 Hand Torque Multiplier with Anti Wind-Up Ratchet and Sliding Reaction, 1” Square Drive supports dependable, repeatable tightening across a wide range of industrial fastening tasks. Because the multiplier handles the torque increase, it can be used effectively in areas where access is limited and where using a large torque wrench would be impractical. For applications requiring enhanced measurement and verification, electronic torque transducers can be fitted for more precise torque monitoring and improved process visibility. If documented calibration is required, a UKAS accredited calibration certificate may be ordered separately. Made in the UK, the HT Series reflects Norbars commitment to durable, precision-engineered torque tools.

The 16089.HD Norbar Standard Series HT1 – HT6 Hand Torque Multiplier with Anti Wind-Up Ratchet and Sliding Reaction, 1” Square Drive are ideal for heavy maintenance, plant operations, rail, utilities, shipyards, and large equipment service where high torque and limited access often go hand in hand. They are especially valuable on structural bolts, large flanges, and machinery fasteners where safer manual torque multiplication, optional monitoring, and reliable repeatability improve both productivity and control.
