A combination construction anchor bolt and retainer for poured concrete installations includes an anchor bolt retaining sleeve which contains an anchor bolt and which is adapted for attachment to a concrete form such that it is imbedded in poured concrete after removal of the form. The sleeve has a single point along its length where its inside diameter matches the bolt outside diameter but the sleeve inside diameter tapers outward from that dimension both above and below that point. This dual tapered design allows the anchor bolt to be adjusted slightly after concrete has been poured and set around the sleeve. The sleeve includes a bolt head retaining pocket and a plurality of wings which prevent it from turning after concrete hasset around it.
