Wedge-lock fastener and associated installation and assembly methods

摘要

A wedge-lock fastener (40) is provided in which the distance by which the tongue (76) protrudes beyond a workpiece (42) may be controlled. The wedge-lock fastener may include a shank (46) and an adjustable spacer member (54) mounted upon the shank and adapted for controlled lengthwise movement relative thereto so as to adjust the position of the tongue with respect to the workpiece. Correspondingly, a method for installing a wedge-lock fastener (40) is provided in which the respective forward ends of the tongue (76) and tongs (60) are inserted through aligned holes defined by two or more workpieces (42,88) and the tongs are then retracted to clamp the workpieces together with the respective forward ends of the tongue and the tongs being disposed completely within a counterbore defined by a workpiece.
