Smart bolts that monitor themselves –144 times a day – 24/7 – every 10 min

Built-in sensors measure bolt condition every 10 minutes and deliver data straight into our monitoring system.

So you can act months before failure, not after.

144 inspections per day

Every 10 minutes. Automatic. 24/7.

Monitor from anywhere

Real-time alerts, trends and full history. All in one dashboard.

Months before failure

Early warning, not late discovery. Plan the stop – don't react to it.

Why Strainlabs?

From invisible risk to full visibility – in three steps

  1. Smart bolts with built-in sensors
    Our bolts measure preload every 10 minutes – automatically detecting changes caused by heat, vibrations or mechanical load.
  2. Automatic data transfer
    Readings are sent wirelessly to our monitoring systems. No manual collection. All data at the same place.

  3. Alerts and trends where you already work
    Monitor bolt condition in real time, track changes over time, and get alerted before small shifts become costly failures.

THE CHALLENGE

The invisible problem

Manual inspections require downtime, provide limited information, and only show a snapshot of bolt condition at a single point in time.

Meanwhile, critical bolted joints are exposed to heat, vibrations and mechanical forces, around the clock. Between inspections, there is no data. Problems are discovered after damage has already occurred.

The result: unplanned downtime, safety risks, and costs that could have been avoided.

Customer stories

What our customers say:

Greger Spetz

Maintenance Technical Manager, Boliden Mines

“Our unit drives maintenance improvements and helps implement new technologies we believe add value across all Boliden sites. We now have two Strainlabs applications running in Garpenberg. One is on the jaw crusher, where it’s extremely difficult to inspect or even detect if the bolts are loose – we want that data-driven. The other application is mobile – a rotating shaft on a vehicle that moves around. Our underground machines have good connectivity, and we want to explore how we can integrate bolting data with other data sources to gain an even deeper understanding of our equipment and its condition.”

Andreas Jälmarstål

Technical manager, Railway at Øresundsbron

“We aim for the most data-driven and smart maintenance possible, and we have an ambition for the facility to notify us when it needs attention. The bridge is designed to last 200 years – we have 175 years left, and we are already looking ahead to what will happen further down the road. We don’t wait for needs to arise; instead, we work proactively towards more AI and machine learning. We want to move away from traditional calendar-based maintenance, which is why this is an interesting pilot project.”

Better understanding of bolted joints

Modern fastening training is undergoing a transformation. Thanks to experts like Markus Fischer, educational initiatives in Germany are updated to better equip engineers and technicians to master the complexities of bolted joints. By combining theory with practical tests and live demonstrations, these courses foster a deeper understanding of how to ensure joint safety and long-term performance.
