CBI Offroad Fabrication and our partner company, Prinsu Design Studio, will no longer use helical spring washers (split ring lock washers) in our product manufacturing, design and engineering, or installation processes.
After extensive research and testing, accompanied by dedicated engagement with experts from NASA (yes, the National Aeronautic & Space Administration) and our engineering team, we gathered and were presented with evidence that shows this hardware is not required to achieve the maximum fixed strength we expect from our mounted products. As a result, we’ve made the decision to exclude this hardware from future product construction and installation.
From this point forward, you’ll no longer receive these pieces (helical spring washers) along with your product delivery. They are not required to perform your installation, and we recommend that you don’t include them – as they will not improve the connection and/or its strength.
