Abstract
Disclosed are various exemplary embodiments of a lock for a ground engaging tool. The lock may include a head portion and a C-shaped portion extending from the head portion. The C-shaped portion may include an inner surface extending between a first circumferential end and a second circumferential end to define a lock slot. The inner surface may include a first inner surface extending from the first circumferential end to a midpoint between the first circumferential end and the second circumferential end and a second inner surface extending from the second circumferential end to the midpoint. The first inner surface and the second inner surface may be symmetrical with respect to a first plane substantially parallel to a lock rotation axis. On a plane substantially perpendicular to the lock rotation axis, a distance between the first circumferential end and the second circumferential end may be less than a maximum distance between the first inner surface and the second inner surface in a direction perpendicular to the first plane.
