• Torque Wrenches for Coaxial Connectors or Polaris^® Lock Nuts
• Preset Torque Values Between 1.5 and 8 lb-in
• Engraved for Easy Identification

Features

• Break-Over Design Ensures Proper Mating Torque is Supplied
• Preset Torque Values Prevent Over-Tightening
• Each Torque Wrench Engraved with Preset Torque Value, Torque Direction, Wrench Size, and Item #
  • Serial Number Engraved on TQW4A, TW6, TW13, and TW18 Torque Wrenches

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.

• Preset Wrenches for Coaxial Connectors (See Table G1.2 for Compatibility):
  • TQW4A: 6 mm Hex, 4 lb-in Torque
  • TQW5A: 5/16″ Hex, 5 lb-in Torque
  • TQW8A: 5/16″ Hex, 8 lb-in Torque

These torque wrenches have a preset torque value to ensure that the proper amount of torque is supplied when mating two coaxial connectors. The TQW4A is set to provide 4 lb-in of torque, which is ideal for 1.0 mm connectors; the TQW5A is set to provide 5 lb-in of torque, which is ideal for most SMA connectors; and the TQW8A is set to provide 8 lb-in of torque, which is ideal for 3.5 mm, 2.92 mm, 2.4 mm, 1.85 mm, K, and V connectors.

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. The torque wrench should be held at the load-point line inscribed near the end of the handle; holding the handle at a different location will affect the amount of torque applied to the connector. The specified torque is guaranteed only when tightening in the direction indicated by the arrow engraved on the handle. Each wrench is also engraved with its preset torque value, torque direction, wrench size, and Item # for easy identification in the field; the TQW4A also includes an engraved serial number.

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 US for details.Contact Us
