Tightening control of screws, studs and bolts.

Why check the tightening?

Insufficient, excessive or heterogeneous tightening represents about 30% of static failures, and poor tightening conditions 45% of fatigue failures. They are a recurring problem in all industries: transport, refinery, nuclear, shipbuilding, etc. with a strong financial and human impact. 

Screwed or bolted joints represent high risk for many industrial companies. It is therefore essential to measure the tightness of screws and bolts accurately. However, most existing methods lack precision or reliability to be repeatable over time.


What solution to control the tightening?

To address this challenge, ULTRA RS have developed State of the Art ultrasonic devices for tightening control. The propagation of ultrasonic waves makes it possible to measure the tightening tensions, without altering the parts and materials of the assembly. This tool, simple to use, fast and transportable, is above all much more precise than a torque wrench. It therefore considerably reduces the risk of error compared with traditional tools.
