A loop-forming tool for forming a loop in a conductor has a grip with a first end section having a central post and an off-axis post mounted therein. The two posts are spaced to allow a conductor to pass therebetween and to grip the conductor when the tool is rotated, bending the conductor around the central post to form a U-shape. Rotating the tool in the opposite direction changes the U-shaped hook to a “?”-shaped hook for attaching to a tie-down bolt. Index marks can be provided on a terminal surface of the first end section to facilitate making consistent loops. The relative sizes of the posts can be configured to allow the tool to also serve to wrap the loop around the tie-down bolt, and to provide a screwdriver for subsequently tightening the tie-down bolt to secure the looped conductor thereto.
