Abstract
Disclosed are various exemplary embodiments of a lock for a ground engaging tool. In one exemplary embodiment, the lock may include an upper portion having a tool interface configured to receive a tool for applying torque about a lock rotation axis, a lower portion including a base located opposite the tool interface along the lock rotation axis, and an insert layer positioned between the upper portion and lower portion. The insert layer may be configured to allow the upper portion to move relative to the lower portion without shearing when torque is applied to the tool interface of the upper portion.
