A wise man told me, “there is something in a name.” Snap ring pliers are a tool designed to install and remove snap rings. Which are those small metal rings that hold in a bearing or other assembly item by setting into a machined groove. Snap rings are common in car engine parts as well as in motorcycle and bicycle shocks and forks. Snap ring pliers are an important addition to a tool box because a snap ring is difficult or impossible to remove or install without them.
