Ensure bolt reliability with ultrasonic verification
Bolt-Check is a state-of-the-art ultrasonic measurement device that allows fast and accurate inspections of bolted joints. Its intuitive user platform, ultrasonic technology, and traceability system let you instantly locate bolts in your database and appropriately schedule service and maintenance.
Bolt-Check is suitable for most bolt types and requires no special pre-treatment of the bolts. It can play an important part in maximizing operational time and minimizing failure. Bolt-Check provides a cloud solution with an intuitive bolt management database to store, sort, and examine measured bolts.
Supports all parts of bolt installation and service
Bolt-Check is the most cost-effective bolt verification solution, and it can be implemented at any stage.
By providing accurate condition data for every bolted joint, Bolt-Check enables better service and maintenance planning, reduces unnecessary site visits, and supports lifetime extension strategies—all while maintaining high safety standards.
By using Bolt-Check during the installation of structures, you can achieve documented, data-driven bolt tightening of the desired clamping force, ensuring reliability and accuracy.
By using Bolt-Check when designing and engineering bolted joints, you can optimize your design to reduce material usage by utilizing smaller and fewer bolts, leading to cost and weight savings.
As a bolt manufacturer, you can increase the value of your bolts with Bolt-Check, providing greater benefits for your customers.
Ultrasonic measurement explained
Bolt-Check uses ultrasonic technology to accurately measure bolt elongation, a crucial indicator of whether the correct clamping force has been achieved. A small transducer sends a sound wave through the bolt and measures how long it takes for the echo to return. This return time reflects the bolt’s ultrasonic length.
By comparing the ultrasonic length before and after tightening, Bolt-Check determines the bolt’s elongation. To ensure accuracy, the system automatically compensates for temperature changes that affect both the bolt’s length and the speed of sound in the material.
Because ultrasonic length changes differently than physical length, Bolt-Check uses a built-in, material-specific stress factor to convert the data into true physical elongation. The result is a reliable, fast and non-destructive way to verify preload in bolted joints.
RFID traceability and cloud-based data management
Each bolt is equipped with a unique ID RFID tag, allowing full traceability throughout its lifecycle. Using the Bolt-Check system and the RFID reader (the RFID pen), technicians can scan each bolt to immediately access its measurement history and identification data.
All measurement data is automatically synced with Bolt Manager— a cloud-based platform for managing bolt projects, storing records, and sharing data. When connected to the internet, the Bolt-Check device continuously syncs with Bolt Manager to ensure all documentation is complete, organized, and instantly accessible from anywhere.
