Dr Charles Clifton of the Heavy Engineering Research Association (HERA) advises that he knows of two cases since June 1983 where correctly specified and marked bolts failed due to the bolt material not meeting the specification. In both instances the bolt shank fractured while the bolts were being fully tensioned.

Given that wider instances of problems with defective and counterfeit bolts have been reported in Australia, it is important that specifiers and construction reviewers follow the quality assurance procedures described in this article to minimise the likelihood of these problems arising in New Zealand.
