The scoops on each of a pair of fastener stringers are formed of a continuous filament bent in a zigzag configuration. Each scoop is U-shaped, consisting of a pair of parallel spaced legs and a coupling head interconnecting the legs at the front end of the scoop. Either of the two legs of each scoop is made longer than the other leg and is folded over toward the coupling head to provide a folded portion which is located between the legs in registered relationship. The front ends of the folded portions of each two adjoining scoops on each stringer are interconnected by a front connecting portion which is so positioned relative to the scoops that when the scoops on both stringers are coupled together by a slider moving therealong, the coupling head of every other scoop on each stringer will abut on the corresponding front connecting portion on the other stringer. It is possible in this way to uniformly determine the meshing depth of all the scoops on the pair of stringers.
