The Hygienic DESIGN fastening system was specially developed for use in food processing facilities. Special attention was paid to the cleaning-optimised geometry and a surface finish of Ra ≤ 0.8 µm. The quick and easy installation due to a pre-installed sealing washer rounds off the overall package.

The surface of the cap nut is polished and, with regard to design optimised for the use in hygienic environments. The top of the nut is spherical and the collar has a conical formed top face. The nut has been designed as a low version so as to keep troublesome corners as few as possible. Due to the extremely high quality surface finish of much less than Ra 0.8 µm, hardly any dirt particles adhere to the surface.
