Hexagon thin nut DIN 439 2 Steel Plain 04 M45

This range of hexagon thin nuts, conforming to established international and national standards including DIN 439-2, ISO 4035, ASME B18.2.4.5M, NEN 2334-B, and NF E25-405-1, provides a reliable fastening solution for a multitude of industrial applications. Manufactured from steel, these nuts feature a plain finish, offering inherent material protection suitable for environments where specific corrosion resistance treatments are not required or are applied post-installation. The Class 040 designation ensures compatibility with corresponding bolts up to property class 4.6, delivering foundational mechanical integrity in assemblies. Each nut is designed with a standard right-hand metric thread, facilitating straightforward integration with compatible threaded components, such as standard bolts, studs, or machine screws. The hexagon drive configuration allows for efficient tightening and loosening using conventional tooling. Primarily employed as jam nuts, these thin nuts are engineered to secure primary fastening nuts against vibrational loosening or to provide a low-profile bearing surface in constrained spaces. Their robust construction and adherence to multiple industry standards make them a versatile choice for engineers and maintenance professionals seeking dependable components for general assembly, machinery, and structural applications where space efficiency and basic performance are critical.
