Blue Hygienic Retaining Washer M12, 20mm Diameter by Wds components

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 parts of hygienic fastening systems. A standout feature of these washers is their cleaning-optimized geometry, enabling thorough and efficient cleaning processes. They also boast an exceptionally smooth surface finish, with a Ra ≤ 0.8 µm classification, ensuring minimal surface irregularities that could harbor contaminants. These washers are produced using food-grade POM material, conforming to both EU10/2011 and FDA standards, making them suitable for use in food and pharmaceutical industries, among others. The POM material offers reliable performance across a temperature range of -20°C to +100°C. A key advantage is their food-grade material, highlighting their suitability for hygienic environments. Available in a striking blue (RAL5002) for visual distinction, they are not suitable for applications involving highly acidic cleaning solutions with a pH below 4 or oxidizing agents. Users are encouraged to assess the compatibility of Hygienic Design fasteners with their specific applications, considering factors like temperature, cleaning agents, and product supports. Regular inspections and replacements, as needed, are recommended to maintain optimal performance. Industries that can benefit from these Hygienic Design washers include food and beverage, pharmaceutical production, and any application where maintaining high levels of hygiene and cleanliness is crucial. They are particularly useful in environments where adherence to strict food and pharmaceutical safety regulations is essential.
