发明名称 THREADED INSERT FOR DRY WALL
摘要 A threaded insert for drywall having an externally threaded portion and an unthreaded drilling portion of generally equal lengths. The insert is adapted to be installed in a single step with the use of a hand powered screwdriver. A low profile flange at the upper end spaced a distance from the threads allows the insert to be installed flush with the surface of the drywall. Two embodiments are disclosed, one of molded zinc and the other of plastic material. Both embodiments include a drilling portion which can be deflected laterally upon the insertion of a screw therethrough, allowing the use of a single moderate length screw for attaching articles of various thicknesses. The insert eliminates the need to pre-drill a hole with a separate tool.
