WebDec 23, 2009 · This method is often called “angle control” in assembly and “turn-of-the-nut” in construction applications. It is a more fundamentally sound method of tension control. There is always a direct correlation between bolt elongation and bolt tension until the bolt yields, which is not the case with the torque-tension relationship. WebHowever, CSA S16-09 specifies smaller values for 5 per cent slip coefficients, c 1, for these twist-off type bolt assemblies versus those of high strength bolts pre-tensioned to meet the turn-of-nut method of installation. chimpanzee classification kingdom to species https://genejorgenson.com
