The surface treatments give the screws visual, chemical, and mechanical characteristics, allowing the same part to be applied in different conditions. Hassmann has qualified suppliers for applying various types of surface coatings, which will give the screws different kinds of colors, corrosion resistance, and friction coefficients.
In addition to the surface treatment, it is possible to include a locking element in the screw thread, which can be mechanical or chemical. These locks seek to provide additional security to the assembled component to prevent the screw from loosening during application. Each type of lock has a specific feature specially developed for a particular application.
