DIN 1587, UNI 5721 Blind hexagon nuts are a versatile and functional solution for protecting screw ends while improving the aesthetics of structures. These blind nuts, thanks to their closed design on one end, prevent the accumulation of dirt and protect threads from wear and corrosion. DIN 1587 and UNI 5721 specifications define the standard dimensions and tolerances of these components, ensuring compatibility with a wide range of applications. They are particularly useful in environments exposed to dust, moisture or chemicals, where thread protection is essential. Blind hex nuts are available in different sizes and materials, such as galvanised steel, stainless steel and brass, to suit specific strength and style requirements. Their hexagonal shape allows quick and safe installation using standard spanners. Using DIN 1587 blind nuts not only improves the functionality of the fastening, but also contributes to a cleaner and more professional design. They are ideal for furniture, machinery, metal structures and decorative applications.
