Certified Hygienic Nuts - Overview of Groups and Features
The certified hygienic nuts with blue sealing provide a secure solution for machinery in wash-down environments by blocking out water and bacteria. The design matches standard nuts, simplifying the upgrade process. NGI's nuts are ideal for floor-mounting hygienic levelling feet to meet hygiene design regulations, with the NDXH variant suitable for varying bolt thread lengths.
- Certifications and Standards: Our nuts are certified in line with 3-A (RPSCQC) and EHEDG hygienic standard TYPE EL - CLASS I AUX, ensuring they meet stringent industry hygiene standards.
- Material and Sizes: Constructed from high-quality AISI 304 and AISI 316 stainless steel, our nuts are built to withstand rigorous sanitation demands. They are equipped with seals available in blue, black, and white colours, crafted from NBR, HNBR, EPDM, FKP, and silicone materials. Available sizes range from M4 to M24 (UNC ¼” to 1”), with Metric F and UNF available upon request. For any sizes not listed, please reach out to us.
- Construction Details: Our nuts maintain standard dimensions, such as wrench sizes and thread heights, which makes upgrading from non-hygienic standard nuts straightforward. The surfaces of these nuts are designed to achieve a maximal roughness of 0.8 μm Ra, effectively minimizing areas where bacteria can accumulate.
- Ease of Installation: Designed for easy replacement and upgrade, our hygienic nuts integrate seamlessly into existing setups, facilitating installation without the need for additional adjustments.
- Product Benefits: Equipped with blue sealings, our nuts not only block out water and bacteria but also prevent non-hygienic metal-to-metal contact, significantly enhancing the cleanliness of your production equipment. Their self-draining surfaces with finely controlled roughness help to minimize dirt accumulation and reduce the risk of contamination.
