On-site Bolt Audits

A bolt audit is an inexpensive insurance policy against the unknown. We do on-site bolt auditing and measurement to verify residual elongation, tension, and percentage of yield.

On-site Ultrasonic Bolt Measurement

We provide trained, experienced technicians along with the latest ultrasonic bolt measurement instruments to accurately measure and document that your bolts have been tightened to within the OEM specifications.

On-Site Supervision of Ultrasonic Bolt Measurement Teams

Many projects already have an ultrasonic bolt measurement system on-site; however, the mechanics or technicians have little or no experience performing this type of work. In these cases, it is advisable to contract for supervision of the team performing the work, eliminating the risk of instrument operation and procedure errors which can lead to erroneous measurements.
