Versatile application options: Thanks to the integrated hole, the magnets can be screwed simply. They are also ideal as a hook or eyelet magnet if they are equipped with a hook or eyelet. High quality coating: The triple Nicuni coating made of nickel, copper and nickel not only offers a durable surface, but also additional protection against corrosion and abrasion.
