An apparatus for assembling a fastener blank to a washer including a mechanism for supplying washers in a sequential manner from unoriented bulk to a desired oriented position and a mechanism for supplying fastener blanks having a shank and a head to a desired oriented position. The apparatus further includes an adjustable fastener driving mechanism for gripping individual fasteners by the shank from the fastener supply mechanism and inserting the fastener shank within an aperture of a respective washer with a very high degree of accuracy and low rate of rejection to accommodate fastener blanks having mis-shaped heads or heads which are off-center or off square with respect to the shank.
