Abstract: A connector in the form of a modified top hat section for securely attaching a building panel to a support member is provided with a guide to assist in accurately locating the fasteners used to attach the connector to the support member with respect to the support member and to guide movement of the fastener as the fastener is rotatingly driven through the connector into the support member to maintain the correct orientation of the fastener to securely attach the connector to the support member. The guide can have a multitude of different forms such as holes, perforations, slots, notches, grooves, lines of weakness and be continuous or in spaced apart relationship to each other. The advantage of the guide is to reduce installation time and effort as well as allowing the top hat section to be securely attached to the support by the fastener having clearance between the strengtheners of the connector and the tapering side wall.
