Except that what you have pictured is called a threaded nail with a spring steel washer. All of the nail type buttons come with any length nails for different thicknesses. The two button backs in the front right are called prong buttons, and the button backs on the left are for eye buttons. The two button backs on the top center are smooth nail no-dent button backs which can also be held with the spring steel washer.
No one lives forever, the trick is creating something that will.
