BELKNAP’S MARKING PRESET TORQUE WRENCHES are designed and recommended for FINAL TORQUE VERIFICATION only, and are not intended to be used for torquing down the fastener. They will leave a positive mark (ink or indentation) for torque verification, so that a simple visual inspection is all that is needed to confirm that torque has been applied. THEY WILL NOT MARK ACCIDENTALLY. All marking torque wrenches are custom made to suit your application.

INK MARKING Preset Torque Wrenches

  • Accuracy is ± 4%.
  • Only marks in CW direction.
  • Manually operated.
  • Non-coagulating ink, includes two ink cartridges.
  • Available ink colors are Red, Blue, Yellow, Green and White.
  • Felt tip left uncovered after long periods of time may require minimal priming.
  • Approximate ink cartridge cycles is 350-400 and dependent upon the operator/application.
  • Ink is also available by the quart.
  • Cannot mark any type of screws, including Allen or Torx (but may be able to mark an adjacent area.)

Hex Size A.T.F. (across the flats) and Torque Limitations — TOP Ink Style

• The smallest we can mark is 1/2″ or 12mm.
• Torque Range is 4-135 Ft.Lbs. or 5.4-183 Nm*

Hex Size A.T.F. (across the flats) and Torque Limitations — SIDE Ink Style

• The smallest we can mark is 9/16″ or 14mm.
• Torque Range is 5-135 Ft.Lbs. or 6.8-183 Nm*

*NOTE: Please check your requirements with us. Torque output capacity will be limited by the Socket size or the Opening size of the head.

PUNCH MARKING Preset Torque Wrenches

  • Accuracy is ± 4%.
  • Only marks in CW direction.
  • Requires 90 psi standard, non-lubricated shop air.
  • Replaceable striking pins will eventually become a bit dull and will need to be easily re-sharpened on a belt sander.
  • Approximate striking pin cycles are application dependent. In our lab tests, we obtained a minimum of 300 punches before resharpening and 10 resharpenings before replacing.
  • Cannot mark any type of screws (but may be able to mark an adjacent area.)

Hex Size A.T.F. (across the flats) and Torque Limitations — TOP Ink Style

• The smallest we can mark is 1/2″ or 11mm.
• Torque Range is 4-150 Ft.Lbs. or 5.4-203.4 Nm*

Hex Size A.T.F. (across the flats) and Torque Limitations — SIDE Ink Style

• The smallest we can mark is 9/16″ or 14mm.
• Torque Range is 4-150 Ft.Lbs. or 5.4-203.4 N*

*NOTE: Please check your requirements with us. Torque output capacity will be limited by the Socket size or the Opening size of the head.
