Certified Hygienic Bolts - Overview of Groups and Features
NGI proudly offers a range of certified hygienic bolts designed to enhance sanitation and efficiency in production environments. Our bolts are tailored to reduce cleaning time and resource consumption, ensuring a cost-effective and hygienic solution.
- Certifications and Standards: Our bolts 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 bolts 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 bolts maintain standard dimensions, such as wrench sizes and thread heights, which makes upgrading from non-hygienic standard bolts straightforward. The surfaces of these bolts 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 bolts integrate seamlessly into existing setups, facilitating installation without the need for additional adjustments.
- Product Benefits: Equipped with blue sealings, our bolts not only block out water and bacteria but also prevent non-hygienic metal-to-metal contact, significantly enhancing the cleanliness of your production equipment.
