Endurabolt – A New Approach to Managing Safety-Critical Bolted Joints

 

Endurabolt is a next-generation structural fastener developed to address long-standing limitations in how safety-critical bolted joints are designed, installed, and managed throughout their service life.

Unlike conventional fasteners, which rely on inferred torque values and periodic inspection, Endurabolt measures load directly within the fastener at the point of elongation.

This enables engineers to move from assumption-based decisions to evidence-based insight, improving confidence in joint integrity, asset life, and risk management.
