Not always. Torque can vary due to friction and lubrication, which affects bolt tension.
Not always. Torque can vary due to friction and lubrication, which affects bolt tension.
Torque is often used as an installation method, but torque readings do not always reflect true bolt pretension. Factors such as thread condition, lubrication, washer surfaces, and friction can cause significant variation. A Skidmore Calibore tool measures actual bolt tension directly, which provides more accurate verification than torque-only measurement. This is why Calibore testing is widely used in structural bolting compliance.
Renting provides access to specialized bolt testing equipment without the cost of purchasing and maintaining it.
Yes, they typically include the required gauge or measurement system.
Yes. Calibore tools can verify hydraulic bolting system performance.
Yes. They are commonly used to verify the bolt tension produced by impact tools.
It depends on the model, but many Calibore tools test common structural bolt sizes from 3/4 inch to 1-1/2 inch.
Inspectors require Skidmore testing to confirm bolting methods meet specification pretension requirements.
A Skidmore Calibore tool is used to measure bolt tension and verify proper pretension during structural bolting.
