SEALING SCREWS - LISI Automotive Innovation

Published on 11 May 2022

Electrification plays a key role in the automotive industry with an increasing number of electrified vehicles. Faced with this massive electrification of the car fleet, the problem of sealing takes a considerable place in the challenges of today and tomorrow.

Indeed, water, dust, etc. are becoming major challenges in automotive assemblies and more generally for the industrial sector. As a specialist in automotive fastening solutions, our teams of experts have developed a brand new range of sealing screws.

ADDED VALUE / Sealing Screws

Our range of sealing screws has different versions:

  • Metal-Metal sealing screw:
    • Sealing ensured only by metallic contact
    • Low cost
    • High tightening torque
    • No creeping effect
    • Geometry that does not destroy the surface (soft metal)
  • Sealing screw with sealed coating:
    • Presence of a sealed coating under the head with low thickness
    • Possible presence of a sealed coating on the thread
    • Less important tightening torque
    • No creeping effect
    • No surface destruction

Sealing screw with sealed coating under head


Our range of sealing screws has been designed with a specific head geometry. The application or not of a sealed coating allows our screws to be used in many cases of application. Depending on the chosen solution, this can be applicable to self-tapping screws for example.

Our solution can be used wherever sealing is required, for example to respond to the challenges of fastening battery packs. Our sealing screws can be used for the automotive sector, and more broadly for any industry with sealed assembly issues.


Thanks to the combination of the multidisciplinary knowledge of our teams, our range of sealing screws has been designed to meet your fastening and sealing problems.
Our experience in fasteners and our expertise in the field of screws, allow us to offer you the most effective solutions for each of your needs.
