A TORQUED BOLT ISN'T ALWAYS A TIGHT BOLT.

Torque doesn't measure tension, it measures rotational force. The friction between the bolt head, threads, and mating surfaces absorbs most of what your wrench applies before it ever becomes clamp force.

Torque Applied

The wrench reaches the specified value.

85–90% Lost to Friction

Absorbed under the bolt head, in the threads, and between mating surfaces.

10–15% Becomes Bolt Stretch

Only a fraction of applied torque translates into useful tension and actual clamp force.

Torque tells you what was applied. Tension tells you what is holding the joint together.

MEASURE WHAT MATTERS

SmartBolts® are the original tension-indicating fastener designed to enhance safety, reliability, and efficiency in bolted joints.

The Visual Indication System™ shows bolt tension in real time, so your team can check critical connections faster, reduce uncertainty, and prevent loose bolts from becoming bigger problems.

CRITICAL JOINT INSPECTIONS

Reduce Inspection Time

Visually verify bolt tension in seconds, no manual torque checks.

Increase Production

Minimise unplanned downtime and keep your equipment running.

Mitigate Risk

Identify tension loss early to prevent failures and safety incidents.

Eliminate Live Work

Verify bolt tension from a safe distance protecting your people.

TRUSTED WHERE FAILURE IS NOT AN OPTION.

“We were looking for a system where we could visually verify the tightness of the bolts. We want our customers to have complete confidence that our shiploader will operate reliably and safely.

The clear visual indication of a loss of tension is reassuring to workers and inspectors alike — and I was really happy to see the consistent results when we tested the heavy duty SmartBolts.“
