It works with regular bolts, high-strength bolts, and stainless steel bolts. You do not need to change your tools.
The entire product line is fully customizable.
FAQ
Q: When would I need a product instead of a standard flat washer?
A: Use thick flat washers when your application has high clamping forces. We also recommend them when the bolt hole is in a soft material that may deform under load.
Q: What is the hardness specification?
A: Our standard products have a 38-45 HRC hardness. For special applications, we can supply up to 50 HRC.
Q: Do you provide load testing services?
A: Yes, we can perform compressive load testing for each batch. We provide full test reports with force-deflection curves.
