Abstract
An improved anchor device or fastening member which is particularly suited for use in the attachment of various fixtures and equipment to masonry, concrete, and other hard and/or friable substrates includes a head and a shank depending therefrom. The shank has a first threaded portion having a predetermined thread angle and a predetermined hardness, and a second threaded portion having a predetermined thread angle and a predetermined hardness. The first threaded portion is proximate to the head and the second threaded portion extends from the first threaded portion. The thread angle of the first threaded portion is different than the thread angle of the second threaded portion. In addition, the hardness of the first threaded portion is softer than the hardness of the second threaded portion. This provides for a more ductile anchorage when the fastening member is engaged with the substrate.
