What BoltSafe does
BoltSafe is a Dutch industrial sensor manufacturer headquartered in Beuningen, Netherlands, specializing in bolt load measurement for safety-critical bolted joints. The company designs and produces compact magnetoelastic load cells (CMS, CMS-NC, and CMS Fusion variants) plus a washer-shaped Smart Washer, and complements these with a portfolio of six readout methods ranging from a handheld reader and wired networks to LoRaWAN IoT nodes and BLE 5.2 wireless loggers. The underlying proprietary technology exploits the Villari effect to convert mechanical stress into electrical signals, enabling full-surface measurement, internal calibration, and drift-free operation with 1% maximum deviation across an 18 kN–3000 kN load range in an IP66-rated form factor.
BoltSafe sells primarily to enterprise customers in the wind energy, civil engineering, power generation, and heavy industry verticals, with named users including Vestas, Enercon, Siemens, Suzlon, TenneT, ASML, Mammoet, Jan de Nul, Hollandia, Freyssinet, DEME, Metso, ERIKS, Hytorc, and research organizations TNO and ITER. Pricing is quote-based with no publicly disclosed rates, and revenue is generated through hardware sales of sensors and readout devices plus ancillary engineering services. The company distributes through direct sales from its Netherlands base and is actively recruiting international distributors, and has localized its website into English, Dutch, German, and French.
BoltSafe operates as a trade name under the Dutch holding company Industrial Bolting Technology and Supply Group B.V. (IBTS group), which also owns sister entities Hytorc Nederland, Hytorc Fasteners, Hytorc Projects, and Total Flange Care. The company employs roughly 15 people led by Managing Director Christian van Kortenhof and founder/R&D lead Mathieu van Kortenhof, maintaining in-house production, calibration, and R&D capabilities with over 20 years of specialized experience in bolt load sensing.

BoltSafe product offering
Product offeringCore offering
BoltSafe designs, manufactures, and sells magnetoelastic bolt load sensors (load cells and smart washers) together with a family of readout devices (handheld, network, IoT, and BLE) used to measure and monitor bolt force in industrial bolted connections. The offering targets wind energy, civil engineering, power generation, and heavy industry customers that need accurate, drift-free, IP66-rated load data for both spot checks and permanent structural-health-monitoring installations.
Product overview
BoltSafe offers a comprehensive portfolio of bolt load measuring solutions centered on magnetoelastic sensor technology. The core product line includes three bolt load cell variants: CMS Bolt Load Cell, CMS-NC Bolt Load Cell, and CMS Fusion Bolt Load Cell. These compact sensors are complemented by six readout methods: Handheld Reader (SM-300), Network with PDI, Network with PDI-NT, RS-232 and Analog Converter, IoT-node (LoRaWAN wireless), and BLE-node (Bluetooth wireless). The Smart Washer completes the product range as a washer-shaped load sensor. All products work together as an integrated system where sensors are placed under nuts on bolted connections and data is transmitted to various readout devices for real-time monitoring.
