A push button release mechanism for coupling together two portions of a tool, such as pliers. The push button release mechanism can include a push button and one or more balls pushed in a radially-outward direction by geometry of the push button to pivotally couple the two portions together. The balls are normally pushed outward by an engagement portion. Depressing a push button head axially downward causes the balls to align with a receiving portion, which allows the balls to descend into the interior of the mechanism. The push button release mechanism is also threadably coupled with a threaded opening of one of the portions. The threaded opening can have deformed threads to increase the retention torque required to rotate the push button release mechanism. 1. A tool comprising:first and second portion pivotally coupled together by a push button release mechanism, wherein the first portion includes a first opening adapted to axially and slidably receive the push button release mechanism, and the second portion includes a threaded opening adapted to threadably couple to the push button release mechanism, and a push button axially movable between first and second positions and including a receiving portion having a receiving portion outer diameter and an engagement portion having an engagement portion outer diameter and extending axially from the receiving portion;', 'a sleeve defining a cavity within which the push button moves axially, the sleeve including external threads and a ball opening;', 'a ball disposed within the ball opening; and', 'a biasing member adapted to bias the push button axially outward from the cavity to the first position and substantially align the engagement portion with the ball when axial force is not applied to the push button, wherein when axial force is applied to the push button, the push button is adapted to be disposed in the second position to align the receiving portion with the ball., 'wherein the push button release mechanism ...
