An anti-lash nut assembly for installation on a threaded rod and including a lead nut, a collar, and a spring positioned between the lead nut and the collar. The lead nut has a set of tabs extending radially outward from a rear end of the body. The collar has a set of clearance slots on an inside surface. The set of clearance slots are configured for sliding of the set of tabs through the clearance slots in the rear direction. The collar has a set of ramps on an inside surface. Each of the set of ramps is configured for engagement with each of the set of tabs to prohibit axial movement of the collar in the rear direction.
