Impact Gun Testers

Because hydraulic load cells actually measure bolt tension not torque we must use specially designed and lubricated Test Bolt Assemblies for testing purposes. We measure the tension that these installation tools are able to generate in the Test Bolts and then divide the Tension by an appropriate "Torque Factor" to arrive at an "approximate" torque value.
