Skidmore Calibore Tool Rentals
Skidmore Calibore tool rentals provide accurate testing and verification of bolt tension and fastener installation for structural bolting applications. These tools are widely used in construction, bridge work, steel erection, and infrastructure projects where bolt pretension must meet specification requirements.
Skidmore-Wilhelm Calibore devices are commonly used to confirm that torque wrenches, impact tools, and bolting systems are producing correct bolt tension. They are essential for compliance with structural bolting standards and inspection requirements on many large construction projects.
Hydraulic Rentals supplies Skidmore Calibore tool rentals for projects throughout New York, New Jersey, and Connecticut. To confirm bolt size compatibility and testing requirements, call 866-522-5464 and speak with a rental specialist.
What Is a Skidmore Calibore Tool?
A Skidmore Calibore tool is a bolt tension calibration device used to measure the actual bolt pretension generated by tightening equipment. Instead of guessing whether a wrench or impact tool is producing the correct bolt load, the Calibore provides a direct measurement of bolt tension.
Skidmore tools are widely used in structural steel erection projects because they help contractors and inspectors verify compliance with bolting specifications such as required pretension levels. They are commonly used for calibrating installation methods for high-strength bolts.
The Calibore system typically includes a heavy-duty frame, hydraulic load measurement components, and a gauge or readout system that displays the applied tension.
Key Features & Benefits of Skidmore Calibore Tool Rentals
Skidmore Calibore tool rentals provide accurate bolt tension verification for critical bolting applications.
Accurate bolt tension measurement
Calibore tools provide direct measurement of bolt pretension to confirm correct installation.
Supports inspection and compliance requirements
Many structural bolting projects require verification testing and documentation for inspectors and engineers.
Improves bolting reliability and safety
Proper bolt pretension is critical for structural integrity and long-term connection performance.
Calibrates torque wrenches and impact tools
Skidmore tools are commonly used to confirm that bolting equipment is producing the correct results.
Essential for steel erection and bridge construction
These tools are widely recognized in the industry as the standard for bolt tension verification.
Cost-effective rental option
Renting provides access to specialized testing equipment without purchasing high-cost calibration systems.
Common Applications for Skidmore Calibore Tool Rentals
Skidmore Calibore tool rentals are commonly used in structural bolting applications where bolt tension must meet specification.
Common applications include:
- Structural steel erection projects
- Bridge construction and rehabilitation
- Highway and infrastructure bolting
- Tower and transmission structure assembly
- Industrial plant steel construction
- Crane rail and heavy equipment mounting
- Quality control testing for bolting procedures
- Inspection support for high-strength bolted connections
Skidmore tools are commonly required when projects involve A325, A490, or other high-strength structural bolts.
How Skidmore Calibore Tools Work
Skidmore Calibore tools are designed to simulate a bolted connection and measure bolt tension during tightening.
Bolt installation testing
A bolt is installed into the Calibore tool and tightened using the same method planned for the jobsite.
Direct tension measurement
As the bolt is tightened, the tool measures bolt pretension using hydraulic or mechanical measurement systems.
Verification and calibration
The results confirm whether the tightening method produces the required bolt load. If not, the method can be adjusted before installation begins.
This process helps prevent improper bolt installation that could result in structural issues or failed inspections.
Skidmore Calibore Tools vs Standard Torque Testing
Skidmore tools measure bolt tension directly, which is more reliable than torque-only testing.
Torque does not always equal tension
Torque readings can be affected by friction, lubrication, thread condition, and washer condition.
Calibore tools measure actual bolt pretension
Instead of relying on torque assumptions, Skidmore devices confirm the real bolt tension being achieved.
Improves compliance confidence
Structural bolting inspections often require proof that the bolting method meets specification. Calibore tools provide this verification.
For critical bolting work, direct tension testing is widely considered the most accurate approach.
