Such thing as ruining a torque on a bolt?

[Hellbound13]

So I know a lot of us like to check those track bar bolts and make sure they are torqued to 125 ft lbs. and have not worked themselves loose..

My questions is, can you do any harm by doing this often with a torque wrench? Will there be a point that a bolt can't take it anymore or should it be fine since you are using a torque wrench and not over torquing?

Food for thought?

My $.02. You can damage a bolt by over tightening. What I would do is set the torque wrench to 100ftlbs and check to see if it moves. Then try 115ftlbs. Then 120. If it doesn't move I would assume its right and wouldn't worry about it. Besides if it moves @ 100 you can just skip to 125 and torque it. That's what I'd do.

But wouldn't setting to 125 prevent over tightening it anyway? THe bolt will always move until the tabbed nut on the other side catches anyway, then if it moves from there it is loose..

You are correct. No need to creep up on it if you are just checking torque.
Applying the correct torque is fine.

Thanks for clarifying Ron but can do this too often lead to any issues?

No. If the bolt is loose, it needs to be retorqued (or replaced, along with the nut).
If it is not loose, it will not move. No harm done.

Ah ok thanks just was not sure if the initial movement of the nut spinning until it catches the welded tab was having an effect on anything.

Not an issue.
