Product Description

Our Flange Nut, precision-manufactured from A4-80 (316) stainless steel to the DIN 6923 standard, is the ultimate solution for highly corrosive and demanding environments. This high-strength nut integrates a hexagonal body with a wide, serrated flange, eliminating the need for a separate washer and providing a permanent, vibration-resistant locking mechanism. The A4-80 grade stainless steel offers exceptional resistance to saltwater, chemicals, and extreme temperatures, making it indispensable for marine, offshore, and chemical processing applications. The polished, non-porous surface also meets hygiene requirements for food and pharmaceutical industries. Engineered for reliability and longevity, this nut ensures a secure, maintenance-free connection where failure is not an option.

Application Scenarios

This nut is specified for critical applications where corrosion and vibration are major concerns:

  • Marine and Offshore Engineering: Essential for boat building, deck hardware installation, offshore platform construction, and underwater fittings due to unparalleled saltwater resistance.
  • Chemical and Pharmaceutical Processing: Ideal for reactor assembly, piping systems, and equipment fabrication where resistance to aggressive chemicals and acids is required.
  • Food and Beverage Industry: The preferred choice for food processing machinery, mixers, conveyors, and brewing tanks thanks to its hygienic, easy-to-clean, and non-contaminating surface.
  • Architectural and Coastal Construction: Used in seaside facades, handrail systems, and bridge components exposed to harsh weather and de-icing salts.
  • Water Treatment and Desalination Plants: Critical for filter systems, pump connections, and valve assemblies in both fresh and saltwater environments.
  • High-Temperature Applications: Suitable for exhaust system components and industrial ovens due to its stability at elevated temperatures.
