A precision adjustment fastener mechanism comprises a base, a platform, and a locking push-pull fastener assembly. The base has a first aperture and the platform has a second aperture. The fastener assembly is disposed within the second aperture. The fastener assembly comprises a clamping fastener having a portion positioned in the first aperture, a sleeve having a third aperture extending along an axis of the sleeve. The clamping fastener is positioned within the third aperture. The sleeve comprises a first portion moveable relative to a second portion along the axis. The first portion and the second portion each comprise outer threads. An axial displacement portion separates the first and second portions and transmits a torque between the first and second portions. The axial displacement portion facilitates movement of the first and second portions to bind threads of the first and second portions with the threads of the platform.
