An integral clamp and screw in the shape of an L has a panel supporting leg and a leg from which a screw projects through and beyond the panel supporting leg. The clamp is used to support a building panel while aligning said panel over the framing members to which it is to be attached and while fastening the panel to said members. The screw is turned into a framing member, such as a ceiling joist or wall stud, by turning the clamp by hand until the panel support leg is close enough to hold the panel loosely against the member, putting the panel into place and then turning the clamp further until the supporting leg holds the panel tightly against the framing member.
