80 oz-in Torque Wrench, 5/16" Hex
TQW8A 8 in-lbs torque wrench used to secure a 2.92 mm connector. The break-over design ensures that the proper mating torque is supplied.
24 oz-in Torque Wrench, 6 mm Hex
32 oz-in Torque
Wrench, 13 mm Hex
- Break-Over Design Ensures Proper Mating Torque is Supplied
- Preset Torque Values Prevent Over-Tightening
- Engraved with Preset Torque Value, Torque Direction, Wrench Size, and Item #
Thorlabs' Torque Wrenches provide preset torque values to secure either coaxial connectors or Polaris lock nuts. When the preset torque value has been achieved, the break-over design will cause the pivoting joint to "break," as shown in the image above. This will prevent further force from being applied to the connector. The wrench's hex head will move back into place once the force is removed.

How come the TW-Series dont work with the 1in polaris piezos since they are 12mm

Hello, thank you for your feedback. We are looking into offering a 12 mm torque wrench for our piezos.

- Ideal for Use with Our Premium Microwave Cables and Adapters
These 5/16" torque wrenches have a preset torque value to ensure that the proper amount of torque is supplied when mating two coaxial connectors. The TQW5A is set to provide 80 oz-in of torque, which is ideal for most SMA connectors, while the TQW8A is set to provide 128 oz-in of torque, which is ideal for 3.5 mm, 2.92 mm, 2.4 mm, 1.85 mm, K, and V connectors. Each wrench is engraved with its preset torque value, torque direction, wrench size, and item # for easy identification in the field.
The preset torque value for each wrench is guaranteed for one year from the date of purchase. If necessary, wrenches may be returned to Thorlabs for recalibration; please contact Tech Support for details.

Each wrench is engraved with its preset torque value and item #.
- Hex Size: 6 mm, 13 mm, or 18 mm
- Three Calibrated Torque Values Available:
- TW6: 24 oz-in for POLARIS-LN05 Lock Nut
- TW13: 32 oz-in for POLARIS-LN1 and POLARIS-LN4 Lock Nuts, as well as POLARIS-T2 Spanner Wrench
- TW18: 48 oz-in for POLARIS-LN3 Lock Nut
- Ideal for Applications Requiring Long-Term Locking
These torque wrenches have a preset torque value to secure the lock nuts on Polaris mounts for long-term locking; see the table below for specifications. Each wrench features a break-over design that allows the wrench to pivot at a joint, as shown to the right. Engraved guidelines indicate the angle the wrench should pivot in order to apply the specified torque; pivoting the handle past these guidelines will over-torque the lock nut. Each wrench is also engraved with its preset torque value, torque direction, wrench size, and item # for easy identification in the field.
These wrenches are designed to be compatible with cleanroom and vacuum chamber applications. They are chemically cleaned using the Carpenter AAA passivation method to remove sulfur, iron, and contaminants from the surface. After passivation, they are assembled in a clean environment and double vacuum bagged to eliminate contamination when transported into a cleanroom. Every wrench has a bead blasted finish to minimize reflections when working with setups that include lasers.
Please note that these wrenches are not intended for use in applications where adjusters are frequently tuned, as these applications typically require torque values of 4 to 8 oz-in (0.03 to 0.06 N·m).
