Screw locking - what does this have to do with surface technology?

Screwlocking means coatings which, for example applied to a thread, prevent loosening of screws or even seizure or corrosion of threaded connections.

The process

The range of coatings that can be applied to screw connections is as vast as the range of requirements in the most varied fields in which such connections are used. As a surface refining specialist, we always ensure that our coatings protect surfaces for a long time and that they provide the best functionality possible. The experts at our plant in Obrigheim, Germany, are working hard on innovative methods to coat screw connections and ensure this protection. In addition to our own processes, we work with high-quality products from renowned manufactured such as Loctite, 3M and Precote. Our solid know-how enables us to efficiently utilize proven quality.

  • Properties

    We use a diverse range of adhesives supplied by the global leaders to glue the screws into place. Their outstanding properties:

    • High pressure-tight
    • Special coating for fine threads
    • High-performance connections with accelerated hardening
    • Very good temperature resistance
    • Low, controlled thread friction
    • UV marker, white or yellow

    Almost all of the screw lockings that we use meet the requirements of DIN 267-27. Screw adhesives that form a seal as soon as they are installed are particularly popular in the construction industry.

    We use only high-quality premium brands with the strongest values to reliably seal screw fittings:

    • Resistant to gas, air and liquid
    • High temperature-resistance
    • Completely sealed immediately upon installation
    • Can be used repeatedly
    • Outstanding resistance to solvents
    • Approved for use by the Deutscher Verein des Gas- und Wasserfaches e.V. (German gas and plumbing association)
    • Suitable for use in pipelines or as captive screw
  • base material

    Preferably, components made of iron and steel alloys are coated.

  • Application

    Our precoatings for connecting elements allow us to treat large quantities of parts and maintain the highest quality throughout. Our thread locks are used primarily in the automotive industry and the construction industry – where people and machines have to be reliably protected. We coat all kinds of connecting elements, in many different sizes and screw variations, to make them more secure and to improve sealing:

    • Screws
    • Nuts
    • Grub screws
    • Special parts such as elbow fittings
