Bolt Stress Tester

The AT 2618 Bolt Tension Tester uses ultrasonic technology to accurately measure the mechanical stress in bolts during tightening.
It performs measurements without damaging the bolt. The device can simultaneously display clamping force, tension, and bolt elongation.
This instrument features two independent measurement channels. Both channels support both longitudinal and transverse wave measurements, enhancing accuracy while also significantly expanding the range of bolt sizes that can be accommodated compared to single-channel devices.

Equipment Features

Measuring bolt elongation, axial load, and mechanical stress
Measurement modes: EMAT, PET
Suitable for bolts ranging from M6x16 to M36 x300
Axial load measurement range: from 0.1 ton to 100 tons
Measurements can still be taken even if the bolt surface has a non-conductive coating.
Connect to a PC for data transfer and reporting

Frequently Asked Questions

Can't charge the device?

The device may have been left unused for too long, causing the battery to lose charge. You can try charging it for an extended period. If there’s still no response, we recommend sending it in for repair. Also, please use the dedicated charger provided for each device when charging.

Can't connect the thickness gauge's flat plate to the instrument?

First, turn on the tablet’s hotspot and check whether the eight-digit number in the hotspot name matches the eight-digit SN code of the device. If they don’t match, make the necessary adjustments. Then, follow the instructions in the manual to connect the tablet. If you’re still unable to proceed, we recommend contacting customer support for assistance.

How can I fix the issue of fluctuating readings during thickness measurement?

It is recommended to connect the flat plate during the thickness measurement process and observe the waveform. If the waveform appears poor, switch to manual mode for inspection. If no consistent waveform is detected, consider potential material issues or probe damage—replace the probe and try again. If no waveform still appears after replacing the probe, the material itself may be of poor quality, making it unable to generate an effective signal.
