Toothed Lock Washers DIN 6797
Product Overview
Toothed lock washers are essential components in the mechanical fastening world, designed to prevent loosening caused by vibration and torque. These washers, compliant with DIN 6797 standards, feature serrated or toothed edges that bite into the surface of the fastened parts, providing a high friction locking power between the bolt/nut and the assembly. Toothed lock washers are most commonly applied in electric, electronic, automotive, aerospace, and heavy machinery industries where strong, vibration-resistant joints are required.
At Flybear Fastener, we supply a wide range of DIN 6797 toothed lock washers fabricated under strict quality control parameters to meet diverse industry demands. Their compact size and high performance make them a trusted solution for aggressive application environments.

Material Introduction & Production Process
DIN 6797 toothed lock washers are primarily manufactured using stainless steel (A2, A4 grades) and carbon steel, offering excellent durability, corrosion resistance, and mechanical strength. The production process includes precise stamping, heat treating, and surface treatment steps to ensure the highest consistency.
The typical production flow includes:
- Raw Material Inspection
- Precision Pressing/Stamping
- Heat Treatment Process
- Surface Coating (Zinc, Black Oxide, etc.)
- Dimensional Accuracy Check
- Packaging and Sorting
All washers are produced under ISO 9001:2015-certified manufacturing environments for quality consistency.
Typical Applications and Industries
Toothed lock washers are widely used across heavy and precision industries:
- Electronics and Circuit Boards
- Automotive Assemblies
- Electrical Panels and Terminals
- Aerospace Fastening Systems
- Engines and Machinery with Vibrational Loads
- Renewable Energy Equipment Mounts
Their anti-slip and anti-loss capabilities make them ideal in scenarios where vibrations cause traditional fasteners to loosen.

Inspection & Quality Control
Our toothed lock washers undergo rigorous quality control processes to ensure optimal performance. This includes:
- Dimensional Inspection with precision gauges
- Hardness and tensile strength tests
- Surface treatment evaluation (salt spray test up to 96hrs+)
- Random sampling and third-party certifications upon request
Each batch comes with traceability and full documentation to ascertain compliance with international standards, including DIN 6797.
Selection and Buying Guide
When selecting the right toothed lock washer, consider the following parameters:
- Material and Corrosive Environment: Choose stainless steel for marine or chemical applications.
- Internal or External Tooth Design: Internal for smooth exterior finishes, external for greater grip.
- Size Match: Fit the washer appropriately to the bolt diameter.
- Surface Coating: Zinc-plated for general use, black oxide for minimal reflectivity.
Custom orders are welcome, and customers can provide drawings or application parameters for tailored production.
Additional Design Benefits
Due to their tooth design, these washers provide exceptional resistance to loosening without damaging the mounting surface in most cases. Featuring a low profile and easy integration into current joints, they’re often favored in automation and high-vibration machinery.
The internal tooth design also supports electrical continuity in grounding applications.
