How to Choose the Best Notched Washers
Understanding Notched Washers
Notched washers, also known as Nord-Lock washers or locking washers with teeth, are designed with internal and external teeth. When tightened, the external teeth bite into the surface of the fastener and the connected material, while the internal teeth grip the bolt head or nut. This creates a secure locking mechanism that resists loosening caused by vibration or thermal expansion.
Key Features to Consider
- Material: Common materials include steel (often zinc-plated for corrosion resistance), stainless steel for environments prone to rust, and sometimes hardened steel for heavy-duty applications.
- Size and Diameter: Washers must match the bolt or screw size. Check the inner diameter (ID) to ensure it fits the fastener shank and the outer diameter (OD) to confirm it covers the intended surface area.
- Tooth Design: The number and sharpness of the teeth influence the locking strength. Some designs offer more aggressive biting action for high-vibration environments.
- Coating/Plating: Coatings like zinc plating offer basic corrosion resistance. Stainless steel options provide superior protection in wet or corrosive conditions.
Applications for Notched Washers
These washers are particularly useful in situations where loosening is a significant concern. Common applications include:
- Machinery and equipment subject to vibration
- Automotive and transportation components
- Construction and structural assemblies
- Any joint where reliability is critical
Choosing the Right Type
When selecting, consider the environment and the stress the joint will endure. For standard indoor use with minimal vibration, basic steel versions might suffice. For outdoor use, marine applications, or high-vibration machinery, stainless steel or hardened steel variants with more robust tooth designs are recommended.
Comparison Tips
- Always verify the washer's inner diameter matches your bolt or screw size precisely.
- Compare the outer diameter to ensure it provides adequate bearing surface without being excessively large.
- For critical applications, look for washers made from high-quality materials like hardened steel or specific grades of stainless steel.
- Consider the manufacturer's specifications regarding load capacity and vibration resistance if available.
Frequently Asked Questions
What is the primary function of a notched washer?
The primary function of a notched washer is to prevent fasteners from loosening due to vibration or thermal expansion. Its internal and external teeth create a strong locking action against the bolt head/nut and the clamped surface.
Are notched washers reusable?
Generally, notched washers are designed for single-use applications to ensure maximum locking effectiveness. Reusing them may compromise the integrity of the teeth and reduce their ability to prevent loosening.
What materials are commonly used for notched washers?
Common materials include steel, often with zinc plating for corrosion resistance, and stainless steel for enhanced durability in corrosive environments. Hardened steel is used for heavy-duty applications.
How do I choose the correct size notched washer?
You need to match the washer's inner diameter to the diameter of the bolt or screw you are using. The outer diameter should be appropriate for the bearing surface required for your specific application.
Can notched washers be used with different types of nuts and bolts?
Yes, notched washers are designed to work with standard nuts and bolts. They are placed between the bolt head or nut and the surface being clamped to provide the locking action.
When should I choose stainless steel over regular steel notched washers?
Stainless steel notched washers are recommended for applications exposed to moisture, chemicals, or outdoor elements where rust and corrosion are concerns. Regular steel washers are suitable for drier, indoor environments.
