Dear Sir,

Dear Sir,
You have to check the threading depth too.
means it might happen that to overcome looseness of nuts , mfgr has decrease the core dia so as to increase the thread height.
Or
you can check its tensile properties by direct breaking.

You can send damaged bolt for tensile testings. Sometime the bolts also fails due to over tightening. Please check with the manufacturer for correct tightening torque.
