An improved fastener stock is comprised of a pair of longitudinal and continuous side members to which are coupled to a plurality of equidistantly spaced cross-pieces. The pair of longitudinal and continuous side members are extended in a parallel spaced relationship, and the series of cross-pieces are arranged at spaced intervals between the side members so as to connect the side members. Along at least one of the side members, a series of engagement notches are present at spaced intervals between each of the cross-pieces members, and the engagement notches are rectangular or square in shape. A method of applying a fastener to an article is provided. The method includes initially feeding a substantially continuous fastener stock from a supply, engaging at least one engagement notch, urging the fastener stock forward, feeding the fastener stock to a needle assembly, cutting a fastener from the fastener stock, and inserting the fastener into an article.
