A small fastener is a type of device used to hold two or more objects together. Common examples of small fasteners include tacks, brads, and snaps. Tacks are small nails with a flat head that are used to attach fabric or paper to a wall or other surface. Brads are thin metal pins with a pointed end that are used to join two pieces of wood or other materials. Snaps are small metal discs with two parts that are pressed together to secure two pieces of fabric.
