Snap fastener

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.

They were also adopted for use with law enforcement holsters and their myriad accessories for similar reasons – replaced in both fields largely by hook and loop fasteners in recent decades.

Press studs were adopted by rodeo cowboys from the 1930s onwards, because these could be quickly undone if, in the event of a fall, the shirt became snagged in the saddle.

[citation needed] Faux pearl snaps entered American mainstream Western fashion during the 1950s, when singing cowboys like Gene Autry and Roy Rogers incorporated them into their embroidered and fringed stage shirts.
