Abstract: Lead screw nuts having a body having a threaded opening having a thread region formed from a plurality of different materials having different properties, e.g., a thread region formed from a first material, such as a relatively low friction material, and a second material, such as a relatively high strength material (having thread portions formed from the first material and thread portions formed from the second material).

Abstract: 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.
