The plates of the connection are … WebA term with many meanings in engineering. One is the tension (load) that is created in a fastener when it is initially tightened. As the bolt stretches, the components between the bolt and the nut compress, thus increasing the so-called clamp load until the end of the tightening process.

An initial preload is introduced so that the compression in the flanges is never completely relieved and hence the flange faces never separate. In order to obtain this level of preload, the bolt is usually prestressed very near its working limits (usually 65 to 90 percent of its yield strength). ウエルシア チラシ 南足柄市
