Abstract
An electrically insulated anchor device is described, comprising a rigid elongated metal sleeve including an external surface that leads from an open top end to a bottom end. A longitudinal internal bore is formed within the sleeve with a bore wall spaced from the external surface by a sleeve wall thickness dimension. An electrically insulative polymer insert with an external surface engages the bore wall within the sleeve. The insert further includes a fastener receiving bore defined by a fastener receiving wall spaced from the external insert surface by an insert wall thickness dimension. The sleeve wall thickness dimension is substantially greater than the insert wall thickness dimension.
