An installation head for use with captive panel fasteners. The head is adapted for mounting onto a conventional fastener installation tool that can apply a predetermined outer axial compressive force distributed about a predetermined inner axial tensile force. The pulling head transfers the outer axial compressive force to an inner axial compressive force delivered to a flaring anvil, while at the same time transferring the inner axial tensile force to an outer axial tensile force delivered to an internally threaded bushing that accommodates the threaded shank of a captive panel fastener. Using the tool and the installation head to apply the predetermined axial tensile and compressive forces, captive panel fasteners can be reliably installed using a single tool stroke.
