Patent ID: 8371017

Claim:
A panel fastener head assembly for installing captive panel fasteners into holes in a panel, said head assembly comprising: means for transferring a predetermined outer axial compressive force to an anvil; said anvil adapted for flaring the end of a captive panel fastener; and means for transferring a predetermined inner axial tensile force to a bushing outside of and coaxial with said anvil; said bushing adapted for retaining a shank of a captive panel fastener; wherein: said head assembly is combinable with a fastener installation tool, the tool having a pulling device for providing said axial tensile force and a pushing device for providing said outer axial compressive force distributed about said inner axial tensile force; and said means for transferring an outer axial compressive force is slidable axially and reciprocally relative to said means for transferring an inner axial tensile force.
