The Van F. Belknap Co. Ink Marking Torque Wrenches will leave a positive mark on a nut, bolt or stud end when the preset torque value of the torque wrench is reached: IT WILL NOT MARK ACCIDENTALLY. When torque verification is required, the Ink Marking Torque Wrench will provide visual, semi-permanent proof that the bolted connection was torqued.

Give it a try!

We have provided two different series to choose from for your applications. The NSIM (Side Ink Marker) Series is for air conditioning connectors, nuts or bolts where proof-of-torque would be marked on the side of the fastener. The NTIM (Top Ink Marker) Series is for applications where proof-of-torque would be marked on the top of the bolt or the end of a protruding stud. The NSIM Series and the NTIM Series DO NOT require shop air.

Additional applications are:
  • ABS systems, air conditioning systems.
  • Oil injectors and fuel injectors.
