A snap fastener (also called snap, popper, and press stud) is a pair of interlocking discs commonly used in place of buttons to fasten
clothing. 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.
Snaps can be attached to fabric by hammering (using a specific punch and die set), plying, or sewing. For plying snap fasteners, there are special snap pliers.
Snap fasteners were first patented by German inventor Heribert Bauer in 1885 as the "Federknopf-Verschluss", a novelty fastener for men's trousers. These first versions featured an S-shaped spring in the top disc instead of a groove.
