Hexagon Domed Cap Nuts Stainless Steel 316 DIN 1587 A4-80 Acorn Nut

Description The stainless steel hexagon domed cap nuts (DIN 1587, A4-80, 316 stainless steel) offer exceptional corrosion resistance, durability, and secure fastening for demanding applications. These acorn nuts, also known as cap nuts, feature a closed-end dome shape that protects bolt threads, enhances safety, and provides an aesthetically pleasing finish. Ever Hardware provides custom made fasteners and customizable packaging. 1. Superior Corrosion Resistance • Made from A4-80 (316 stainless steel), providing excellent resistance to rust, saltwater, and harsh chemicals. • Ideal for marine, offshore, chemical processing, and food industry applications where exposure to chlorides, acids, and extreme weather conditions is common. • Performs better than A2-70 (304 stainless steel) in highly corrosive environments. 2. High Strength and Durability • Manufactured to A4-80 strength standards, offering superior tensile strength and load-bearing capacity compared to standard stainless steel fasteners. • Withstands mechanical stress, vibration, and impact, making it suitable for structural, heavy-duty, and high-pressure applications. 3. Protective Domed Design • The smooth, rounded cap covers exposed bolt threads, preventing injuries, scratches, and damage to nearby components. • Shields threads from dirt, moisture, and contaminants, reducing the risk of corrosion and wear over time. 4. Secure and Reliable Fastening • Provides a tight, vibration-resistant connection, preventing loosening in high-stress and high-movement applications. • Commonly used in machinery, automotive, construction, and marine industries. 5. Enhanced Aesthetic Appeal • The polished finish and smooth dome shape give a clean, professional look, making it ideal for decorative and visible fastening applications. • Frequently used in architectural, furniture, and automotive designs where both functionality and aesthetics matter. 6. Easy Installation and Compatibility • Designed with a hexagonal shape, allowing for easy tightening with standard wrenches and sockets. • Complies with DIN 1587 standards, ensuring compatibility with metric bolts and threaded rods. 7. Prevents Thread Damage and Galling • The enclosed dome protects bolt threads from environmental exposure, reducing friction, galling, and thread seizing, which is common in stainless steel fasteners. • Ensures smooth assembly and disassembly, even after long-term use in harsh conditions. 8. Ideal for Various Applications • Suitable for marine engineering, offshore structures, food processing equipment, medical devices, and outdoor structures. • Commonly used in bicycles, motorcycles, safety enclosures, and precision instruments where reliable fastening and corrosion resistance are required. Conclusion Stainless steel DIN 1587 hexagon domed cap nuts (A4-80, 316) offer exceptional corrosion resistance, high strength, and protective features, making them ideal for marine, chemical, industrial, and decorative applications. Their secure fastening, durability, and clean aesthetic ensure long-lasting performance in extreme 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-M16 Standard DIN 1587 Dome Type Metal Dome Thread Coarse Thread Material Stainless Steel A4-80/316 Color Silver/Natural
