Description The stainless steel hexagon domed cap nuts (DIN 1587, A2-70, 304), also known as acorn nuts, provide secure fastening, protection, and corrosion resistance in various applications. These nuts feature a closed-end dome shape, covering exposed bolt ends for safety, aesthetics, and durability. Ever Hardware provides custom made fasteners and customizable packaging. 1. Corrosion and Rust Resistance • Made from A2-70 (304 stainless steel), these nuts are highly resistant to rust, oxidation, and moisture, making them ideal for outdoor, marine, and industrial applications. • Suitable for humid, mildly acidic, and corrosive environments, such as food processing, construction, and automotive industries. 2. Protective Domed Design • The rounded cap covers the bolt end, preventing injuries, scratches, and damage to surrounding surfaces. • Eliminates sharp, exposed threads, making them ideal for decorative, furniture, and safety applications. • Prevents dirt, dust, and moisture from entering the threaded section, extending bolt lifespan. 3. Aesthetic and Clean Finish • Offers a polished, professional appearance, improving the visual appeal of automotive, furniture, and architectural designs. • Commonly used in visible fastener applications, such as railings, fixtures, and decorative metalwork. 4. High Strength and Durability • The A2-70 stainless steel composition provides high tensile strength, ensuring reliable fastening in load-bearing applications. • Withstands mechanical stress, vibration, and impact, making it suitable for industrial and mechanical assemblies. 5. Prevents Thread Damage and Loosening • The enclosed dome protects bolt threads from impact, dirt, and corrosion, preserving thread integrity over time. • Reduces the risk of loosening due to external forces, enhancing fastening reliability. 6. Easy Installation and Compatibility • Designed with a hexagonal shape, making it compatible with standard wrenches and sockets for easy tightening. • Follows DIN 1587 standards, ensuring compatibility with metric bolts and threaded rods. 7. Versatile Applications • Commonly used in automotive, construction, furniture, sports equipment, and marine industries. • Ideal for machinery, enclosures, and industrial equipment where protection, aesthetics, and durability are essential. Conclusion Stainless steel hexagon domed cap nuts DIN 1587 (A2-70, 304) offer corrosion resistance, safety, and an aesthetic finish, making them ideal for decorative, industrial, and safety-focused applications. Their protective dome design, durable construction, and secure fastening properties ensure long-lasting performance in harsh environments.   Thread Size M4 M5 M6 M8 M10 M12 M14 M16 M18 M20 M22 M24 Hex A/F 7.0 8.0 10.0 13.0 17.0 19.0 21.0 24.0 27.0 30.0 32.0 36.0 Hex Height 2.9-3.2 3.7-4.0 4.7-5.0 6.14-6.5 7.64-8.0 9.64-10.0 10.3-11.0 12.3-13.0 14.3-15.0 14.9-16.0 16.9-18.0 17.7-19.0 Total Height 8.0 10.0 12.0 15.0 18.0 22.0 25.0 28.0 32.0 34.0 39.0 42.0 Thread Length Min 5.26 7.21 7.71 10.65 12.65 15.65 17.65 20.58 24.58 25.58 28.58 30.5   Size M3-M20 Standard DIN 1587 Dome Type Metal Dome Thread Coarse Thread Material Stainless Steel A2/304 Color Silver/Natural
