Product Selection Differences for Lock Washers

When selecting lock washers, there are several key differences to consider:

1. Type of Lock Washer:

   • Spring Washers: These are designed to compress when tightened, providing a spring-like effect to prevent loosening.
   • Toothed/External Tooth Lock Washers: These have external teeth that bite into the mating surface to prevent rotation.
   • Split Ring Lock Washers: These have a split cut that acts as a spring to create tension between the bolt and the surface.
   • Nord-Lock Washers: These consist of pairs of washers with cams on one side and radial teeth on the other, which lock against the bolt and nut to prevent loosening.

2. Material:

   • Lock washers are commonly made from materials like steel, stainless steel, brass, and plastic. The choice of material should consider factors such as corrosion resistance, strength, and durability.

3. Size and Compatibility:

   • Ensure that the lock washer size fits the bolt and nut size for effective locking.

4. Application:

   • Consider the application requirements, such as the level of vibration, load, and environment, to choose the most suitable type of lock washer.

5. Performance and Reliability:

   • Evaluate the performance characteristics of the lock washer, such as its ability to prevent loosening under various conditions.

6. Cost:

   • Consider the cost implications of the different types of lock washers and choose one that balances cost-effectiveness with performance.

7. Ease of Installation:

   • Some lock washers may be easier to install than others, so consider this factor based on the application requirements.

By carefully considering these factors, you can select the most appropriate lock washer for your specific needs.
