Sammy's #14 Black Nut Driver enables easy and safe installation of Sammy's rod hangers. The custom nut driver bit fits into any drill and is compatible with Sammy's hex screw heads, thereby securing the anchor screw firmly while it is being drilled into a wood, steel or concrete structure. As soon as the installation is complete, this uniquely designed nut driver will spin free on the screw, thereby eliminating wrist snap, over-torque and screw failure. Constructed from the highest quality materials and designed for your convenience, it makes Sammy's installations an absolute pleasure.
