Tornillo auto-perforados con un revestimiento de al menos dos lubricantes sólidos diferentes, en donde el primer lubricante sólido es un termoplástico o una cera y el segundo lubricante sólido es al menos otro termoplástico. A coating agent for fasteners, in particular drilling screws and thread-forming screws, serves to improve the handling safety and reliability. For this purpose, the agent includes at least two different solid lubricants, with the first solid lubricant being a plastic or a wax and the second solid lubricant being at least one further plastic. These solid lubricants are preferably present in a solution, for example in a water-based, alcohol-based, or another, in particular organic solvent-based solution. The solid lubricants are preferably present as a micro-granulate, which achieves a better distribution in the coating and therefore a better availability of the solid lubricants in the case of use. A method for coating such fasteners with such a coating agent is also the subject-matter of the present invention.
