Lightweight, super-strong spring steel. Hang a picture, mirror, or wall accessory of up to 50 lbs. securely, in seconds, and with no tools needed. Self-boring tip enables the hook to penetrate the drywall, with simple hand pressure and a back and forth twisting motion. Then the shaft slides through and with a final push, the self-locking feature locks the Monkey Hook securely in place. Only the hook is exposed and ready for the wall hanging.
