While on the subject of bolts:
Driving down the home stretch I heard a clinking, clanking sound. Walked back up the street and found a Grade 8 washer head bolt. The unthreaded portion of the shank is about 2 1/2" long. The next 3/8" has a deep knurl. There is one tread left at the end of the knurl. Looked all around the '79 C-10 to see where if it could have fell off. No luck so far.
Cannot determine the purpose of knurling at that position on the bolt.
Any ideas?
