Check the Unbrako site for info on this. Note carefully that pretensioning a bolt is as much art as science. There are lots of variables involved, and it's a matter of considerable experience. Don't expect a table on some web site to substitute for a sound knowledge of basics--if you haven't already, do some studying on the topic.
