Visual Indication System™

The Visual Indication System is a method of measuring bolt tension that is embedded in every SmartBolt. This technology uses color to indicate tension. Changes in color are proportional to bolt stretch, ensuring accurate and reliable measurements.

Unmatched Benefits

SmartBolts® improve the safety and reliability of your equipment. A real-time visual alert of tension allows hands-free inspection. Service life is extended with full repeatability, reusability, and no wearable parts. Install and inspect on-the-go with no training required.

Unprecedented Value

Remove the doubt associated with fasteners. Simple installations and efficient inspections reduce operational costs. Furthermore, SmartBolts provide an early warning of reductions in bolt tension, leading to increased productivity and safer job sites.

"Now that we use SmartBolts in our 37 ton Gradall scaling machines, we can make educated decisions about maintenance because we know which bolts need service and how long a shutdown to schedule. As a result, we’re saving tens of thousands in overtime and downtime and our workers are happy to be spending much less time crawling under the Gradall checking bolts."

"We initially had some concern about using these more ‘expensive’ bolts, but after several tests and trials showing their value in added safety, as well as less downtime and visual inspections – it was an easy decision to replace all our mold clamping bolts with SmartBolts. And the appreciation our operators have expressed is priceless!"

"The constant movement of the welding robot was causing the bolts to lose tension. So we decided to retrofit our robots with SmartBolts; now the maintenance technician can look over during welding and visually check that the bolts are secure. This has had a positive impact on improving our overall safety and manufacturing efficiency."

"The three main slewing bearings of our shiploaders connect the base structures to the loading arms and allow them to swing to reach various cargo holds in the ship. As Project Manager, I wanted to be completely confident that the installation crews were getting these critical bolts properly tightened during assembly and that they were staying tight. That’s exactly why SmartBolts are now our standard."

"These devices measure clamp load and not torque. They will also tell you relaxation in the connection [and] allow equipment to be inspected in use without shutdown. They reduce [Preventative Maintenance] costs immensely. The price of these are a cost savings compared to any traditional PM schedule in expensive, safety or mission critical equipment. One breakdown will most likely cost you more than the upfront cost difference in the bolts. I have used them in drive systems in excess of 3000 kN*m output torque and rugged specialty vehicles."
