Press Fits
Press fits are the most common intentional use of residual stress. Automotive wheel studs, for example are pressed into holes on the wheel hub. The holes are smaller than the studs, requiring force to drive the studs into place. The residual stresses fasten the parts together. Nails are another example where the stress created by penetration of wood then helps to keep the nail in place.

Famous quotes containing the words press and/or fits:
“I would have these good people to recollect, that the laws of this country hold out to foreigners an offer of all that liberty of the press which Americans enjoy, and that, if this liberty be abridged, by whatever means it may be done, the laws and the constitution, and all together, is a mere cheat; a snare to catch the credulous and enthusiastic of every other nation; a downright imposition on the world.”
—William Cobbett (1762–1835)
“During the cattle drives, Texas cowboy music came into national significance. Its practical purpose is well known—it was used primarily to keep the herds quiet at night, for often a ballad sung loudly and continuously enough might prevent a stampede. However, the cowboy also sang because he liked to sing.... In this music of the range and trail is “the grayness of the prairies, the mournful minor note of a Texas norther, and a rhythm that fits the gait of the cowboy’s pony.””
—Administration in the State of Texa, U.S. public relief program (1935-1943)
