DIN 6799 Retaining Washers for Shafts, lock washer auto parts GB 896, ASME B 18.27.1

DIN 6799 Lock Washers provide a simple and effective solution to prevent loosening of fasteners due to vibration and movement in various automotive assemblies. Their design allows for quick and straightforward installation under nuts or screw heads.

Key Advantages for Your Automotive Applications:

• Effective Vibration Resistance: Manufactured according to DIN 6799 standards, these lock washers are specifically designed to counteract the effects of vibration and prevent the loosening of threaded fasteners in automotive environments. This is crucial for maintaining the integrity and safety of vehicle components subjected to constant movement and stress.
• Secure Locking Mechanism: The unique shape and elastic properties of DIN 6799 lock washers create a spring force that actively resists loosening caused by rotation or axial movement. This ensures a more reliable and long-lasting connection compared to using fasteners without locking mechanisms.
• Wide Range of Sizes: Available in a comprehensive range of metric sizes, typically from M0.8 to M30 (as indicated in the reference), DIN 6799 lock washers can accommodate various screw and bolt diameters commonly used in automotive construction.
• Material Versatility: Commonly manufactured from spring steel (to provide the necessary elasticity) and stainless steel (for enhanced corrosion resistance), these lock washers can be selected based on the specific environmental and performance requirements of different automotive applications. Surface treatments like black oxide can also be applied for additional protection.
• Simple and Cost-Effective: DIN 6799 lock washers offer a straightforward and cost-efficient method for securing fasteners against vibration, making them a widely adopted solution in the automotive industry. Their ease of use contributes to efficient assembly processes.
• Compliance with Standards: Adherence to DIN 6799 ensures dimensional accuracy and consistent performance, providing reliability and interchangeability in automotive manufacturing and repair.

Ideal for Automotive Applications Such As:

• Securing Components in Engine Compartment: Preventing loosening of bolts and screws on engine mounts, exhaust systems, and other components subjected to significant vibration and heat.
• Fastening Body Panels and Trim: Ensuring secure and rattle-free attachment of interior and exterior trim pieces, which can be prone to loosening due to vehicle movement.
• Electrical Connections: Maintaining secure electrical grounding points and preventing loosening of terminal screws in automotive wiring harnesses.
• Dashboard and Instrument Panel Assemblies: Preventing vibration-induced loosening of fasteners in the dashboard and instrument panel, ensuring the stability of gauges and controls.
• Braking System Components (non-critical): Providing additional security against loosening in certain non-safety-critical components of the braking system.
• General Fastening in High-Vibration Areas: Used throughout the vehicle in various assemblies where vibration-induced loosening is a concern.
