Addressing long-standing structural limitations in bolted joint design that have remained fundamentally unchanged for centuries.
Developed to overcome the long-standing structural limitations inherent in conventional fastener manufacturing, Endurabolt re-engineers the bolt architecture itself — enabling engineers to move beyond legacy failure mechanisms and explore new possibilities in safety-critical joint design.
Unlike conventional fasteners, which rely on inferred torque based assumptions, Endurabolt enables accurate reload measurement at the point of installation — providing greater confidence in joint integrity and supporting improved fatigue performance.
The unique two-piece architecture provides engineered access to the region of highest elongation and stress within the fastener, independent of bolt length or diameter.
This enables engineers to move from assumption-based decisions to evidence-based insight, improving confidence in joint integrity, asset life, and risk management.
Changes failure physics
Endurabolt is a patented, structurally re-engineered fastener designed to reduce fatigue-driven failure by changing how cracks initiate and propagate — not by simply observing a conventional bolt.
Tighten harder. Fail less.
The engineered construction enables safe tightening to approximately 90% preload, reducing joint micro-movement and the fatigue damage typically introduced at installation.
Monitors where failure starts
Monitoring is embedded at the failure-critical region of the fastener, confirming real joint behaviour even when torque appears acceptable and before visible degradation occurs.
Unlocks multi-billion pound savings
By reducing failure probability and removing uncertainty, Endurabolt enables a shift away from conservative inspection, access, and downtime regimes — delivering systemic cost removal at fleet and infrastructure scale.
From Assumption to Evidence
What Endurabolt changes
Endurabolt changes the bolted joint from something that is assumed to be safe into something whose behaviour can be confirmed. The fastener itself is structurally re-engineered to reduce fatigue vulnerability, and monitoring is embedded at the same region where failure would initiate, allowing joint behaviour in service to be validated rather than inferred from torque or inspection alone.
Why this matters
In safety-critical assets, uncertainty around bolted joints drives conservative inspection regimes, repeated access, downtime, and increased safety exposure. By reducing fatigue risk and confirming joint behaviour over time, Endurabolt enables a shift toward condition-based intervention, changing how joints are managed across their service life.
