Nut, an Uncommon card

The card carries these facts from its Wikipedia article.

• The two partners are kept together by a combination of their threads' friction with slight elastic deformation, a slight stretching of the bolt, and compression of the parts to be held together.
• In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: lock washers, jam nuts, eccentric double nuts, specialist adhesive thread-locking fluid such as Loctite, safety pins or lockwire in conjunction with castellated nuts, nylon inserts, or slightly oval-shaped threads.
• Square nuts, as well as bolt heads, were the first shape made and used to be the most common largely because they were much easier to manufacture, especially by hand.
