Colour Marking Wrench for Cap Screw Tightening

A mark is made on the tightened cap screw and an adjacent location on your work. This lets you check for subsequent loosening. A marking torque wrench for tightening cap screws, which prevents human tightening errors.

Upon reaching the set torque the marker is designed to stamp on the bolt and work. Because the stamped mark is put on the side of the bolt and the work piece, it can not only prevent missed tightening but also detect loosening of bolts. The marker is designed to stamp only when the torque wrench operates upon reaching the set torque.

Marking stays on by use of quick dry ink. One refill of ink is capable of approximately 3,000 times of stamping. Marker is ink cartridge type. Only hand force required for tightening a bolt and marking the bolt simultaneously. Applicable for international use including the EU region. Compliant with ISO 6789 Type II Class B calibration procedures.



  • Ratchet head w 24 teeth and 15° operating range.
  • Tightening and marking in a single operation.
  • Accuracy and calibration procedures compliant ISO 6789 type II class B.
