A lifting and leveling assembly configured to be embedded in a precast concrete slab for lifting a leveling a precast concrete slab includes a base plate, a threaded sleeve, an anchor plate, a thread protecting sleeve, a threaded lifting bolt and an end cap. Rotating the threaded lifting bolt in a first direction positions a bolt head on the threaded lifting bolt above a top surface of a precast concrete slab to accommodate the attachment of a lifting device. Rotating the threaded lifting bolt in a second direction positions the bolt head beneath the top surface of the concrete slab and causes the threaded shaft to exert a force on the base plate to level the precast concrete slab.
