Accurate Bolt Tensioning ±2%
Bolt tensioning is critical to the safety, reliability, and performance of any bolted joint. Our Bolt Tension Calibrator provides a fast, accurate, and reliable way to verify the actual tension applied to a bolt during installation. Designed for both field and workshop use, this essential tool ensures that bolts are properly tightened to specification—helping prevent failures due to over- or under-tightening.

What Is a Bolt Tension Calibrator?
A bolt tension calibrator is a device used to directly measure the clamping force (tension) in a fastener as torque is applied. By simulating real-world joint conditions, it allows technicians to confirm that the proper preload is achieved and that torque tools are delivering consistent results.
Key Benefits
- Accurate Measurement: Directly measures bolt tension (preload), not just torque.
- Tool Calibration: Perfect for calibrating impact wrenches, torque wrenches, and tensioning systems.
- Quality Assurance: Ensures every bolt is tightened to engineering specifications.
- User-Friendly: Simple operation and easy-to-read gauges make it suitable for all skill levels.
Applications
Bolt tension calibrators are widely used in:
- Steel construction
- Heavy equipment assembly
- Bridge and infrastructure projects
- Wind turbine and energy installations
- Aerospace and industrial maintenance
Why It Matters
Using a bolt tension calibrator significantly reduces the risk of bolt-related failures, ensures compliance with industry standards, and supports quality assurance efforts across various industries. Whether you're validating a torque method or developing a bolting procedure, accurate tension measurement is essential.
