If threaded parts such as thread forming or thread rolling screws need to be prepared for their specific application, we can meet this requirement and provide partial lubricant coatings. This technology allows different areas on one and the same component – depending on the requirement and application – to be adjusted with varying friction coefficients or sliding properties. The friction of a screw’s thread, for example, could thus be different than that of its connecting surface. We can also use partial lubricant coatings on the inside of the drill holes.
