New Construction Electrical Rough Inspection, what … WebI read that bolts in tension are designed so that the shaft fails before the threads. I would have expected that the threads stripping would be a slower failure(?) and therefore someone could notice the problem before full catastrophic failure, and so that would be the preferred way for them to fail, so just looking for some insight into the reasoning behind this.
