The Hangman Gold Bear Claw Hangers include the BCD double-headed, anchorless screw that works best with D-rings or wire for simple mirror and mirror and picture hanging solutions. Installs with a hand-held phillips screwdriver. No pilot hole required because it has a self-drilling tip for easy installation in dry wall, lath plaster or wood studs. When used with these products the Bearclaw Hanger is hidden from view. Works with plastic anchors if additional holding power is needed. Holds up to 100 lbs.
