Left Hand Threaded Domed Cap Nut DIN 1587 A2-70 Stainless Steel Hexagon Acorn Nuts 304

Description Left hand threaded domed cap nut (DIN 1587, A2-70, 304) combine secure fastening, corrosion resistance, and safety with an anti-loosening feature for specialized applications. These hexagon acorn nuts have a reverse thread direction, making them ideal for situations where standard right-hand threads might loosen due to vibration or rotational forces. Ever Hardware provides custom made fasteners and customizable packaging. 1. Anti-Loosening in Rotating Applications • Left-hand threads tighten in the opposite direction, preventing unintentional loosening in motors, rotating shafts, and machinery with counterclockwise motion. • Commonly used in automotive, industrial, and mechanical applications where vibration or torque could cause standard nuts to loosen. 2. Corrosion and Rust Resistance • Made from 304 stainless steel (A2-70), offering excellent resistance to moisture, oxidation, and mild chemicals. • Suitable for marine, outdoor, and industrial environments where exposure to humidity, water, or corrosive substances is a concern. 3. Protective Domed Design • The rounded cap covers the exposed bolt end, preventing injuries, scratches, or damage to nearby components. • Shields threads from dirt, dust, and corrosion, extending the lifespan of the fastener. 4. High Strength and Durability • Manufactured to A2-70 tensile strength standards, ensuring strong mechanical performance in load-bearing and high-vibration environments. • Withstands moderate mechanical stress and impact, making it suitable for structural and heavy-duty applications. 5. Aesthetic and Smooth Finish • Provides a clean, polished look, making it ideal for visible fastener applications in furniture, automotive, and architectural projects. • Commonly used in decorative metalwork, railings, and outdoor fixtures. 6. Prevents Thread Damage and Ensures Longevity • The enclosed dome design protects the threaded bolt from external elements, reducing wear, corrosion, and mechanical damage. • Ideal for exposed installations where environmental protection is necessary. 7. Easy Installation and Secure Fit • Designed with a hexagonal shape, allowing for easy tightening with standard wrenches and sockets. • Complies with DIN 1587 specifications, ensuring compatibility with left-hand threaded metric bolts and rods. 8. Specialized Industrial Applications • Frequently used in reverse-threaded assemblies, including bicycles, motorcycles, heavy machinery, and safety-critical systems. • Essential in applications where motion or force direction requires a left-hand thread to prevent loosening. Conclusion Left hand threaded domed cap nut DIN 1587 stainless steel (A2-70, 304) offers secure fastening, anti-loosening properties, corrosion resistance, and safety. Their reverse-thread design, protective dome cap, and durable stainless steel construction make them ideal for industrial, automotive, marine, and decorative applications, ensuring long-term reliability in demanding 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 M6-M20 Standard DIN 1587 Dome Type Metal Dome Thread Left-Hand Thread Material Stainless Steel A2/304 Color Silver/Natural
