Types
Washers can be categorised into three types; plain washers, which spread a load, and prevent damage to the surface being fixed, or provide some sort of insulation such as electrical; spring washers, which have axial flexibility and are used to prevent fastening loosening due to vibrations; and locking washers which prevent fastening loosening by preventing unscrewing rotation of the fastening device; locking washers are usually also spring washers. The term washer is also often used for disc shaped devices used as grommets.

Famous quotes containing the word types:
“The rank and file have let their servants become their masters and dictators.... Provision should be made in all union constitutions for the recall of leaders. Big salaries should not be paid. Career hunters should be driven out, as well as leaders who use labor for political ends. These types are menaces to the advancement of labor.”
—Mother Jones (1830–1930)
“The bourgeoisie loves so-called “positive” types and novels with happy endings since they lull one into thinking that it is fine to simultaneously acquire capital and maintain one’s innocence, to be a beast and still be happy.”
—Anton Pavlovich Chekhov (1860–1904)
“As for types like my own, obscurely motivated by the conviction that our existence was worthless if we didn’t make a turning point of it, we were assigned to the humanities, to poetry, philosophy, painting—the nursery games of humankind, which had to be left behind when the age of science began. The humanities would be called upon to choose a wallpaper for the crypt, as the end drew near.”
—Saul Bellow (b. 1915)
