Leg bolts and leg levelers

A missing leg bolt can be replaced with an ordinary 3/8 in bolt 2-1/2 in long; most take standard 3/8 in nuts. Free seized leg levelers with penetrating oil and patience rather than force, which can twist the leg. Leave at least 1/4 in of leveler thread showing above the leg, and lock it with the nut under the leg.
