Hygienic design washers are precision components designed to meet stringent hygienic application requirements. They are intended for use with WDS 7661 hex head bolts or WDS 7662 hex nuts, making them integral to hygienic fastening systems. A standout feature of these washers is their cleaning-optimized geometry, facilitating thorough and efficient cleaning processes. They boast an exceptional smooth surface finish, with Ra ≤ 0.8 µm, ensuring minimal surface irregularities that could harbor contaminants. These washers are produced using EU10/2011 and FDA-compliant thermoplastics, ensuring their suitability for use in food and pharmaceutical sectors, among others. The thermoplastics, known as POM, are resistant to temperatures ranging from -20°C to +100°C, providing reliability under various operating conditions. A significant advantage of these washers is their food-grade material, emphasizing their suitability for hygienic environments. They are available in a deep blue (RAL5002) version, providing visual distinction and aesthetic appeal.
