Stainless Steel Dome Nut Nylon Insert A2 DIN 986 Hex Polyamide Acorn Prevailing Torque Type Hexagon Domed Cap Nuts 304

Description

The stainless steel dome nut nylon insert with a nylon insert are prevailing torque fasteners designed to provide secure locking, vibration resistance, and corrosion protection. Made from A2-70 (304 stainless steel), these hexagon domed cap nuts feature a polyamide (nylon) insert, ensuring they remain firmly in place without the need for additional locking mechanisms. Ever Hardware provides custom made fasteners and customizable packaging.

1. Reliable Self-Locking Mechanism
• The nylon insert increases friction on the bolt threads, preventing the nut from loosening due to vibration, rotation, or shock loads.
• Eliminates the need for additional locking washers or adhesives, reducing assembly time and costs.
• Ideal for dynamic and high-vibration environments, such as automotive, machinery, and industrial equipment.

2. Corrosion and Rust Resistance
• Made from 304 stainless steel (A2-70), these nuts offer excellent resistance to moisture, oxidation, and mild chemicals.
• Suitable for outdoor, marine, food-grade, and industrial applications where exposure to humidity, salt, and chemicals is common.

3. Protective Domed Cap Design
• The smooth, rounded cap covers the exposed bolt end, preventing damage to surrounding components, skin, or fabric.
• Enhances safety by eliminating sharp thread exposure, making it ideal for decorative and furniture applications.
• Provides a clean, finished look for architectural, automotive, and industrial assemblies.

4. Vibration and Shock Absorption
• The nylon insert acts as a cushion, absorbing vibrations and mechanical shocks, ensuring a stable and long-lasting connection.
• Commonly used in motorcycles, bicycles, railway systems, and heavy machinery.

5. High Strength and Durability
• The A2-70 stainless steel composition provides high tensile strength and durability, making these nuts suitable for load-bearing and mechanical fastening applications.
• Withstands moderate mechanical stress while maintaining a secure fit over time.

6. Prevents Thread Damage and Galling
• The nylon insert reduces direct metal-to-metal contact, minimizing the risk of thread galling and seizing, which is common in stainless steel fasteners.
• Ensures smooth and easy disassembly, even after long-term use.

7. Ideal for Various Applications
• Suitable for automotive, construction, furniture, sports equipment, and marine applications.
• Frequently used in safety enclosures, electrical panels, and machine guards due to its protective dome shape.

8. Compliance with DIN 986 Standards
• Manufactured to DIN 986 specifications, ensuring standardized dimensions and compatibility with metric bolts.

Conclusion

Stainless steel dome nut nylon insert DIN 986 (A2-70, 304) offer a secure, corrosion-resistant, and vibration-proof fastening solution. Their self-locking design, protective domed cap, and durable stainless steel construction make them ideal for industrial, automotive, marine, and architectural applications, providing long-lasting reliability and safety.
