You can download the torque chart as a pdf, or you can print what you see on the screen.

Until we dont have the format.Thanks

We have torque values on our website, but every application is a bit different, so there is no one all encompassing torque value that works for all applications. Controlled lab testing is the only sure fire way of determining your specific torque values. http://www.portlandbolt.com/technicalinformation/bolt-torque-chart.html

This is for a transmission line tower.

An engineer would be the best person to consult regarding this.

There is no such thing as an overtightened connection, until you break the bolt in tension. RCSC – Sec. 9.2.4, states: “A pretension that is greater than that specified in Table 8.1 shall not be cause for rejection”

The content of the post has been updated. Thanks for catching that.

It is a twisting force.
