FAQs
What is the inner diameter of these washers?

Troubleshooting
Washer does not fit over the bolt thread
Verify the bolt is an M10 size; if the bolt has a protective coating or thick plating, it may require a slightly larger diameter washer.
Washer appears deformed after tightening
You may be applying excessive torque. Reduce the tightening force and ensure the bolt and washer are perfectly flush with the substrate.
Pros and Cons
Pros
- High-quality brass material resists corrosion
- Meets industry-standard DIN 125A specifications
- Large pack size is cost-effective for trade use
- Prevents surface damage during bolt installation
Cons
- Limited to M10 size applications
- Material is softer than hardened steel washers
- Not suitable for high-tensile structural steel bolting requirements
Setup, Compatibility & Care
To ensure optimal performance, verify that your bolt thread and shank diameter are compatible with the 10.5mm internal diameter of the washer. While these washers are robust, avoid over-torquing them against extremely hard surfaces that may cause the brass to deform. No specialized maintenance is required; however, if the washers are exposed to harsh chemicals, occasional cleaning with a dry cloth will help maintain their bronze finish. Store the remaining washers in their original container to prevent moisture accumulation and ensure they stay organized for future use.
