An improved method and apparatus for assembling washer members with fastener members provides for moving a plurality of one of the fasteners and the washers along a helical path and the other of the fasteners and the washers in a circular path and simultaneously therewith increasing the telescopic assembled relationship between the fasteners and the washers. The apparatus disclosed herein whereby said methods may be practiced includes a base and a wheel having a plurality of pockets about the periphery thereof. The wheel is rotatably mounted on the base and means are provided for continuously rotating the wheel at a predetermined speed. Means are provided for feeding the washers in an oriented position into the pockets in the wheel and means are provided for feeding the fasteners in an oriented position into the pockets in the wheel. A stationary arcuate cam is secured to the base and extends about a portion of the periphery of the wheel after the washers and fasteners are received in the pockets of the wheel. The arcuate cam has an arcuate cam surface for effecting simultaneous relative movement of a plurality of the fasteners and the washers by moving a plurality of one of the fasteners and the washers along a helical path simultaneously therewith increasing the telescopic assembled relationship between the shank portions of a plurality of the fasteners and the washers.
