This is partly because there has not been available an effective quantitative inspection method, and partly because of the "out of sight out of mind" syndrome.
Failures of bolts have occurred in the past and as a result have become a significant cause for concern in operating structures.
One of the main concerns is failure due to corrosion since it often occurs in areas where visual assessment cannot be made.
Since the most common form of corrosion damage is gradual necking of the bolt, traditional zero degree probe ultrasonic scanning from the bolt end fails due to the lack of reliable reflectors from which to assess thickness or diameter loss.
