Abstract

A downhole tool for use in a subterranean well having a casing therein. The downhole tool has a mandrel, a wedge, a slip bank and a pre-set mechanism. The wedge is disposed about the mandrel and in sliding relationship with the mandrel such that the wedge can slide between an unset position and a set position. The slip bank is associated with the wedge such that, when the slip wedge is in the unset position, the slip bank is in a radially inward position and does not engage the casing, and when the slip wedge is in the set position, the slip bank is in a radially outward position and engages the casing. The pre-set mechanism has a first detent ring located between the first wedge and the mandrel and positioned at least partially in a groove in the mandrel. The detent ring prevents the wedge from moving from the unset position to the set position until a load on the mandrel exceeds a predetermined force.
