Prevailing Torque Hex Thin Nuts with Non-Metallic Insert DIN 985: Unwavering Vibration Resistance for Automotive Safety

Introducing our range of DIN 985 Prevailing Torque Type Hexagon Thin Nuts with Non-Metallic Insert – the essential fastening solution for ensuring exceptional resistance to loosening in critical automotive applications.

At [Your Company Name - e.g., a leading supplier of automotive fastening solutions in Switzerland], we understand the paramount importance of secure and vibration-proof connections in the demanding automotive industry. Our DIN 985 compliant hexagon thin nuts are meticulously engineered with a non-metallic insert to provide a reliable locking mechanism, safeguarding the integrity of your assemblies even under the most challenging operating conditions.

Engineered for Ultimate Vibration Security:

DIN 985 specifies low-profile hexagon nuts with a non-metallic (typically nylon) insert within the threaded section. This intelligent design provides a significant advantage in automotive applications prone to vibration and dynamic loads:

  • Positive Locking Mechanism: The non-metallic insert creates friction against the bolt threads as the nut is tightened. This prevailing torque resists loosening caused by vibration, shock, and thermal cycling – critical factors for vehicle safety and reliability.
  • Reusable Locking Action: Unlike single-use locking fasteners, DIN 985 nuts can be loosened and retightened multiple times while still retaining a significant portion of their locking torque. This facilitates maintenance and adjustments in automotive assemblies.
  • Reduced Risk of Damage: The non-metallic insert provides a degree of cushioning, minimizing potential damage to the bolt threads during installation and removal.
  • Space-Saving Design: The thin profile of DIN 985 nuts makes them ideal for applications where space is limited, a common constraint in automotive engineering.

Designed for Ease of Use:

Our DIN 985 Prevailing Torque Hex Thin Nuts are engineered for efficient and reliable integration into automotive assembly processes:

  • Standard Hexagon Shape: Compatible with widely used standard wrenches and automated tightening equipment in automotive manufacturing.
  • Easy Installation: Installs like a standard nut until the non-metallic insert engages with the bolt threads.
  • Versatile Application: Suitable for a wide range of automotive materials and clamping force requirements where vibration resistance is crucial.

Key Advantages for Your Applications:

  • Unmatched Vibration Resistance: Prevents loosening in high-vibration automotive environments, enhancing safety and reliability.
  • Reusable Locking Capability: Facilitates maintenance and adjustments without compromising locking effectiveness.
  • Space-Efficient Design: Ideal for tight automotive assemblies where low profile is required.
  • Reduced Maintenance Costs: Minimizes the need for retightening and reduces the risk of component failure due to loose fasteners.
  • Global Standard Compliance: DIN 985 is a widely recognized standard, ensuring quality and interchangeability.

Ideal for:

  • Chassis and Suspension Systems: Securing components where constant vibration and shock loads are present.
  • Engine and Powertrain Mounts: Ensuring critical engine and transmission components remain securely fastened.
  • Exhaust System Assembly: Resisting loosening caused by engine vibrations and thermal expansion.
  • Steering and Braking Systems: Providing vital security for safety-critical components.
  • Interior and Exterior Trim: Preventing rattles and ensuring secure attachment of panels and accessories.
  • Electrical and Electronic Components: Maintaining secure connections in vibration-prone areas.
