A clip structure to be secured to a work surface by a power actuated tool having a cylindrical barrel member from which a fastener element is driven, the clip structure including a center portion and a projecting retaining flange having spaced corners engaging the side wall of the barrel member at at least two peripheral points thereon having a chordal spacing less than the diameter of the barrel member, and including a projecting attachment flange engaging the barrel member side wall substantially oppositely from the engagement by the retaining flange to loosely retain the clip structure on the barrel member, the attachment flange including a leg portion extending outwardly from the barrel member for pre-assembly with a hanger wire that will not interfere with subsequent disposition of the clip structure on the barrel member. The center portion of the clip structure may be apertured to engage the tip end of the stud element extending outwardly from the barrel member of certain types of tools. Additionally, the tool may be provided with an extension element whereby the tool, with a clip structure placed thereon, may be manipulated to locate the clip structure against a ceiling and then actuated by a workman standing on the floor beneath the ceiling, the preassembled hanger wire depending vertically from the clip structure to form a plumb line providing vertical reference for aligning the tool therewith.
