FASTENINGS & ADHESIVES MEETING AUTOMOTIVE
DEMANDS WITH CONNECTED FASTENING SYSTEMS
Josh Scanlon, area sales manager at Desoutter
Tools, explains how connected fastening systems can help manufacturers in the automotive
industry maintain process control as production environments become increasingly complex
A
s predictable multi- year cycles gives way to shorter timelines
and greater variation, automotive manufacturing is undergoing its most significant change since the introduction of the original assembly line. This is most visible in the rise of mixed- model manufacturing, where ICE, hybrid and electric vehicles are built on shared or rapidly reconfigurable assembly lines. These vehicles pass down
the line, with operators and tools adjusting to different parts, structures and electrical systems as each vehicle or component is built. This reflects a market
still in transition, where manufacturers must support multiple powertrain types in parallel because demand has not settled around a single technology. As of May 2026, the battery electric car market share had crept up by just half a percentage point to 23.1%, still below the 33% share required under the ZEV mandate, underlining the gap between regulatory targets and current demand. This means tier suppliers must increasingly
support multiple platforms, shorter programme cycles and changing specifications without compromising process control.
STRUCTURAL INTEGRITY Fastening sits at the intersection of structural integrity, electrical safety and production execution. Its importance is heightened in electric and hybrid platforms, where it governs battery enclosures, high-voltage systems and lightweight structures. In mixed-model environments, fastening complexity increases significantly, since different vehicle variants require different torque specifications, tightening sequences and joint strategies.
8 This requires connected fastening systems that
integrate tooling, process control and production data within a closed-loop manufacturing architecture. Desoutter’s connected assembly ecosystem brings together intelligent tools, controllers and software platforms to support tightening execution, process control and production traceability within a single mixed- model manufacturing environment. Within this model, tightening
parameters are defined at system level and assigned according to production inputs, including vehicle variant identification. Connected tools can automatically apply the correct fastening strategy for each application, enabling multiple vehicle configurations to be managed within the same production environment. This enables manufacturers to adapt to production variability while reducing reliance on manual process selection and ensuring the right settings and quality checks are applied. Crucially, each fastening operation
is validated at the point of execution through real-time feedback and process confirmation, ensuring deviations are identified immediately rather than retrospectively. This prevents non-conforming assemblies from progressing downstream and creates a traceable record of critical fastening operations. Tightening data can be captured
and analysed to support process verification, traceability and
Recent recalls have shown how even small
deviations in fastening integrity can have significant consequences. In May 2026, for example, Ford recalled almost 180,000 Ranger and Bronco vehicles after identifying that a front seat frame bolt could become loose or dislodged. Fastening has become a point of process
control where manufacturing variability is either contained or allowed to spread through the rest of the production system. For UK manufacturers operating in high-value, lower-volume environments, maintaining fastening quality while increasing production flexibility is therefore becoming a defining operational challenge.
CONNECTED FASTENING As production environments become more variable, fastening systems must do more than just deliver a specified torque. They must help ensure that the correct fastening process is applied to the correct vehicle, at the correct stage of assembly, every time.

continuous improvement across production runs. Within this framework, fastening becomes a connected process control function embedded within the wider manufacturing system.
MEETING THE CHALLENGE Flexibility has become a prerequisite as manufacturers continue to balance ICE, hybrid and electric vehicle production. The ability to control variability at the point of assembly will determine how effectively they can scale changing production strategies while maintaining quality. Fastening sits at the centre of this challenge.
By connecting execution, verification and production data, manufacturers can turn a traditionally fixed assembly operation into an adaptable process control point, enabling greater flexibility without compromising consistency.
