SmartBolts
Know at a Glance it’s Tight
SmartBolts are tension indicating fasteners that offer real-time visual indication of bolt preload. A visual indicator simplifies the installation and inspection process.
When you know at a glance that a bolted joint requires maintenance, issues can be identified and fixed before they become problems.

Safety
Limit risk in hazardous areas and prevent accidents. Identify and fix issues before they become problems.
Efficiency
Quickly verify clamp load without touching tools, pausing production, or powering down equipment.
Reliability
Clear and repeatable preload reading that meets the toughest standards.
DTI Visual Indicator
The DTI Visual Indicator is a color-calibrated real-time display of tensile load. The indicator is bright red when the fastener is loose and gradually transitions to black when the fastener is tightened to its desired tensile load, or Design Tension.
Visual Indication
Quick visual inspections from a distance.
Real-Time Feedback
Tensile load is measured and displayed without delay.
High Visibility
Vivid color display ensures maximum clarity.
Unlimited Cycles
Completely reusable with continuous functionality.
Customizable
Meet application-specific preload requirements.
Compatible
Fully compatible with all standard tools.
We recommend the use of a DTI Verification Guide to inspect a SmartBolts Visual Indicator. DTI Verification Guides are supplied with every order of SmartBolts. Contact us to request additional supply.
Watch a Demonstration
Watch the DTI Visual Indicator respond in real-time to the changes in tension by changing color: red when loose and black when tight. We recommend watching in full-screen mode for best results.
In this demonstration a bolt tension calibrator stretches a SmartBolts from 0% to 100% Design Tension, then returns the SmartBolts to 0% Design Tension. The demonstration features a SmartBolts with a design tension of 40.6 klbf (40,600 pounds-force).
In this demonstration a hydraulic torque wrench tightens a SmartBolts from 0% to 100% Design Tension, then the tool loosens the SmartBolts to 0% Design Tension. The demonstration features a SmartBolts with a design tension of 100 klbf (100,000 pounds-force).
