Abstract
Continuously connected fastener attachment stock formed by elongated plastic side members with cross coupling links. One of the side member has successively connected cross bars with each cross bar connected to one of the cross links. The other side member has successively connected head pieces with each head piece connected to one of the cross links. The stock is proportioned to be fed as an entity to a position within a machine where individual fasteners are sparated from the stock, with each separate fastener including a head piece, a cross bar, and coupling link interconnecting the head piece with the cross bar. Each cross bar is configured for feeding through the bore of a slotted hollow needle.
