What is "snap fastener"

n. a pair of male/female interlocking disks used to fasten a piece of clothing in place of buttons

n. a fastener used on clothing; fastens with a snapping sound; "children can manage snaps better than buttons" [syn: snap, press stud]

A snap fastener (also called press stud, popper, snap or tich) is a pair of interlocking discs, made out of a metal or plastic, commonly used in place of buttons to fasten clothing and for similar purposes. A circular lip under one disc fits into a groove on the top of the other, holding them fast until a certain amount of force is applied. Different types of snaps can be attached to fabric or leather by riveting with a punch and die set specific to the type of rivet snaps used (striking the punch with a hammer to splay the tail), sewing, or plying with special snap pliers.

Snap fasteners are a noted detail in American Western wear and are also often chosen for children's clothing, as they are relatively easy for children to use.
