Is it true that bolts are impervious to outside forces?
There is a common misunderstanding that a bolt within a securely fastened connection is impervious to outside forces if hey don’t exceed the clamped load of the connection. That is, the myth says a bolt clamped to 500 lbs won’t experience additional stress unless outside forces applied to the clamp exceed 500 lbs.
What happens when you tighten a nut on a fastener?
Both springs stretch measurably, but the weaker one stretches more. Part of the external load is absorbed by the joint and part by the fastener. To be crystal clear, as you tighten the nut the bolt will compress the two parts together.
