Patented Bolt Load Measuring Technology Prevents Leaks – Eliminates Fugitive Emissions

The DTI is a specially designed load measuring device with protrusions on one face.  It is placed under the bolt head or nut, and the protrusions create a gap.  As the bolt is tensioned, the clamping force flattens the protrusions, reducing the gap.  A “no-go” feeler gage is used to insure that the specified bolt tension is achieved.

• Verifies correct tension for secure joints.
• Permanent load verification to +/- 2% of bolt load.
• Bolt load achieved regardless of bolt condition and torque applied.
• Simple to install and inspect with standard tools, no special training.
• Low cost alternative to ultrasonic measuring.
• Customized DTI’s available.
