Abstract
A pivoting adjustment screw for mounting the bolt of a latch to provide vibrational damping along with increasing preload as the contact point of the adjustment screw to the mating structure shifts in a shock or vibrational environment. The adjustment screw includes a pivoting portion which permits the screw to pivot which allows a rotating rather than a scraping or abrading movement in response to the relative movement between the elements being connected.
