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. Contact us now to learn more about our Marking Preset Torque Wrenches.

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.
