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.
