MARKING PRESET TORQUE WRENCHES
Ink & Punch

Marking Torque Wrench

BELKNAP’S MARKING PRESET TORQUE WRENCHES are designed 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.
