Re-useable bolts
Re-useable bolts
(OP)
Is there such a thing as re-useable bolts?
I had read somewhere that it was not good practice to re-use bolts too many times.
Are there any codes or standards that define the recommended number of times that a bolt can be re-used.
Thanks

and seeing very little dynamic loading
cycles, reuse them.

a) the nut could run smoothly along the threads,
b) in wasn't fully torqued previously.
RE: Re-useable bolts
If the bolts are structural, and they have yet to be loaded or fully torqued, then reuse them. If the bolts have seen service loads, or have been torqued to their higher end, toss'em to be safe. Finally, if there are locking features on either the nut or bolt, toss the respective part unless there is specific data to support reuse.
At the company I work for, aircraft OEM, bolts needing to be reinstalled at the factory are not typically tossed as they are 1) very expensive, 2) torqued to values below yield, and 3) some have specific retorquing procedures based on the inherent locking features. However, bolts replace in the field are strongly recommended to be replaced, no matter what condition they appear to be in.
