Re: Anyone Ever Break a Head Bolt - Retorque? Posted by SWEDECAR [Email] ![]() ![]() ![]() In Reply to: Anyone Ever Break a Head Bolt - Retorque?, Steve H., Fri, 28 Jan 2005 05:32:02 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I have not broken a Saab bolt of this newer type bolts that came out in the mid 80s (stretch to yield bolts).
That's when they started to use the angle torque as the last moment.
When I had the problem back in 2001 with the new bolts I could feel how the bolt just gave way and I pulled a little bit furter but finally gave up and took the bolt out.
It had developed a waist line from "giving up" but luckily didn't break.
These torque to yield bolts are more flexible (soft) than other bolts and "give" before they snap off.
