JW Winco, Inc. offers GN 1580 Nuts with Hygienic Design. The GN 1580 Stainless Steel Nuts are certified according to European Hygienic Engineering and Design Group guidelines, making them ideal for use in hygienic areas. “The sealed flange surface enables components to be mounted without dead spaces,” said John Winkler, CEO, Office of the President at JW Winco. “The high quality finish, as well as the large corner radii and closed surfaces, prevent adherence of dirt and facilitate cleaning.” Available in either a matte or polished finish, the FDA compliant sealing ring on the nuts is made of a hydrogenated acrylonitrile Butadiene rubber and is temperature resistant from -25 °C (-13 °F) to 150 °C (302 °F).
