Each Wrench is Engraved for Easy Identification in the Field

• Hex Size: 5/16"
• Two Calibrated Torque Values Available:
  
  • TQW5A: 80 oz-in
  • TQW8A: 128 oz-in
• 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).
