Nitronic 60 Stainless Steel Hex Head Screws for Particle-Free Environments
Made of Nitronic 60 stainless steel, these screws have a slippery surface that keeps them from sticking or binding during installation. Often used in clean rooms, they thread smoothly without coatings or lubricants that could contaminate particle-free environments. These screws also resist corrosion from mild chemicals and salt water. To maintain their friction and corrosion resistance, use them with Nitronic 60 stainless steel nuts (sold separately) and washers. All screws meet ASME or ISO (formerly DIN) specifications for dimensions. Length is measured from under the head.
