The Avid Ringer Aluminum Cap Screws are designed for hardcore racers who want to shave off weight while adding sparkle with our Ringer-influenced design. Aluminum screws have been available for decades, but their strength was an issue as their heads would easily snap off when overtightened or in areas with high stress. However, these screws are surprisingly resilient and have been used on 10th scale buggies in high-stress areas such as shock towers, shock mounts, and wing mounts without any failures.
Compared to kit steel screws, switching to titanium screws saves 40% in weight, while aluminum screws can save up to 60% (Screw weight: Steel 0.5g, Ti 0.3g, Al 0.2g). Although aluminum screws are 33% lighter than titanium, they are not as strong. To avoid stripping the screw head, never use a ball end wrench or electric driver to tighten the screw fully. Instead, use an electric wrench to set the screw snugly, then hand tighten it the rest of the way.
