Thanks to ESTIC’s patented motor control system, our pulse fastening technology has achieved an unprecedented reduction in reaction forces. Torque data is continuously processed every 1/2000 of a second to control the overall fastening strength and ensure safe and highly accurate tightening with minimal reaction force. What’s more, the tool’s ergonomic design and advance pulse fastening technology allow for single-handed operation in certain situations, dramatically reducing the strain placed on the operator.

Self-loosening screws represent one of the most persistent and costly challenges in industrial assembly and manufacturing. Through vibration, thermal expansion and contraction, material creep, and repeated mechanical stress, conventional fasteners gradually lose their clamping force, leading to joint failure, equipment malfunction, and costly downtime.

This presentation explores the fundamental physics behind fastener self-loosening and reveals how traditional solutions are falling short against the increasingly complex demands of modern manufacturing - including ease of automation, assembly reliability, technical cleanliness, and challenging assembly materials.

We present an innovative approach that combines POWERLOK® thread technology with complementary fastening elements to create a robust solution that simultaneously attacks both vibration-induced loosening and material relaxation, illustrated through real-world examples where failure is not an option.

Markus Fischer has many years of experience with screw‑technology audits. He shares some almost unbelievable stories, illustrating just how much untapped potential still lies in this seemingly simple and well‑functioning “screw.”

His message is clear: you should never take anything for granted — not even within your own company.

La solución multifunción que simplifica el montaje, reduce el assortment y aumenta la fiabilidad en entornos exigentes.

ecosyn® elimina pasos, reduce errores y mejora la repetitividad del proceso. Esto permite flujos de montaje más estables, compatibles con automatización y resistentes al aflojamiento por vibración o asentamiento en materiales como aluminio o cobre. Menos piezas, menos manipulación y menos variabilidad se traducen directamente en mayor productividad.

In many production environments, the torque wrench is considered a guarantee for safe bolted joints. Yet even when tools are set correctly, deviations from the target value still occur. The reason: typical sources of error in the tightening process – such as extension length deviations or continued load following click – often go unnoticed in day-to-day operations. The consequences can range from quality issues to safety-critical risks.

This presentation uses practical examples to show where these errors arise, why they often remain undetected in production, and which technological approaches can help make tightening processes more transparent, reproducible and reliable.

A presentation for anyone who believes that tightening with a torque wrench automatically results in a correct bolted joint.

The causes of quality issues in industrial bolting assembly, disruptions in the production process, or component damage are diverse and complex. Every employee can contribute—through theoretical expertise or practical skills—to identifying errors at an early stage or avoiding them altogether.

An experienced trainer and instructor will explain in an engaging and practical manner the potential sources of error in the design process, in the selection of bolting tools, and in defining assembly procedures and monitoring parameters. In addition, numerous real-life examples will highlight critical sources of error in the day-to-day handling of fasteners, components, and bolting equipment.

But how can this urgently needed, proper, and standards-compliant knowledge development be achieved within a company? This interactive presentation introduces an exciting and holistic concept: from qualification analysis to the implementation of traditional training methods and the integration of modern digital learning modules, all the way to individual competency certification.

Needs-based qualification in both theory and practice, efficiency of training measures, effectiveness in knowledge transfer in line with the current state of the art, and compliance with VDI/VDE-MT 2637—these goals can all be achieved simultaneously and do not have to be mutually exclusive.
