Abstract: A button assembly is disclosed which includes a spear that is removably connected to the back side of a button head for enabling penetration of a post (or shank) of the button head through a piece of fabric. The post, itself, is threaded so that a locking disc can be screwed onto the post on the back side of the fabric once the spear has been removed and discarded therefrom. The surfaces of the disc and the button head which engage the fabric are also provided with teeth so that the button is not loosened from the fabric once it has been fastened thereto.
