The Wikipedia has the following information about this codepoint:
A drawing pin (in British English) or [thumb] tack (in North American English), also called a push-pin, is a short, small pin or nail with a flat, broad head that can be pressed into place with pressure from the thumb, often used for hanging light articles on a wall or noticeboard.
Thumb tacks made of brass, tin or iron may be referred to as brass tacks, brass pins, tin tacks or iron tacks, respectively.
These terms are particularly used in the idiomatic expression to come (or get) down to brass (or otherwise) tacks, meaning to consider basic facts of a situation.
