Inspection of the snug-tight bolts

Inspection of the snug-tight bolts

(OP)
What is the best way to inspect snug-tight bolts at pre-engineered metal buildings?

RE: Inspection of the snug-tight bolts

I generally check a few in different locations, just using my hands. However, i always get the steel erectors checking process and certification. Thus that i can be confident that some one has done a check.

Funny thing is that they do not give you these for the purlin bolts, and i normally check a few of these and more often than you would like to think, i find they are loose.
 

When in doubt, just take the next small step.

I sometimes post in a couple of forums; often get a better range of responses...

RE: Inspection of the snug-tight bolts

Snug tight bolts are generally tightened to the max effort from a structural steel erector's 'spud' wrench. If you can check them by hand, they are way too loose. There are several publications, that indicate a torque for 'snug' tight conditions. They are tight enough to generally prevent them from loosening over time.
