Somebody had a bad day... orrr a drunk day.. lol these look untouched, and I very highly doubt this carpet has ever been out. I'm guessing the assembly line had air impacts with preset torque cutoffs, and I'm guessing they just missed the bottom one and it hit the torque spec and the guy thought nothing of it or didn't care. The top one looks like the tunnel cover sealer set too long before torquing of the bolts and that's as fas as she went.

I'll have to look and see if there's been an open gap there or not. As long as they aren't cross threaded or whatever it's not a big deal. 79 k10

My old '83 K5 had a couple of the tunnel bolts installed in a similar fashion. Being a K5, it was assembled at the Flint plant. I'll bet that @Keith Seymore says it was a rather common occurrence. Non structural, covered with a rubber mat or carpet. There was probably much less care given in that area.

Yep.

Don't even ask about fender bolts.

I was hoping to get your input! I assumed since it was a non visible/vital area, it was just glanced over.

I would call it an "after lunch" job. I was in the bar at the Holiday Inn across from the truck plant in Flint one day and it was just me and my amigo and about 6 waitresses. At one point they just start loading up tables with food and drinks. Every place setting had at least 3 drinks, beers, mixed, straight or a combination. All of a sudden the place is packed with guys from the plant on their lunch and I have never in my life seen people drink alcohol so quickly in my life. Twenty minutes and the place was empty again.

I would say we're lucky they even got as close as they did.

Yah - you really probably can't be too hard on the assembler. He likely had an air powered angle driver which was not reversible. So - once the faster started off cockeyed he could only watch helplessly as it rode off into the distance.

There probably was an inspector who should have caught it and written it up, and there was for damn sure a repairman who should have seen it and fixed it. So - really - three people who were having a bad day, not just one (plus the foreman, probably).

Once the insulator and carpet went down - it was long gone and on it's convoluted journey to you.

Normally it's cross threads that are a problem. Some times you can cross thread a bolt and simply power it home with an impact but, if you are not living right, you'll break the little weld nut loose. At that point it's not getting fixed on a moving assembly line; it will have to go to a stationary repair bay out back and the repairman is going to have to take some time to get the broken weld nut out of there and replace it with a regular nut.

We used to have a lot of problem with the fender nose bolts, which attach the front of the fender to the radiator support because it was blind and had awkward access.

We discovered that there were two suppliers for a bolt that same size: One from Lang Fasteners and one from Ferndale Fasteners. The Langs would crossthread like crazy but the Ferndales wouldn't for some unknown reason, maybe because of the difference in coatings. The Langs (part number 3846202, btw!) were black phosphate but the Ferndales were silver cadmium.

What we ended up doing was stealing a box of the silver bolts from Line 2 and run them all night with no issues, and then lock them up in our locker, set out a box of black bolts on the job and then go home.

We did that for several years. First shift could never figure out why we didn't crossthread those bolts and why they had a mess on their hands every day.

The wheel opening moldings are designated by RPO (regular production option) B96.

Sometimes, when installing the moldings, the screws would hit torque but not be fully seated. Rather than grabbing a screwdriver and torquing the screws home my line side repairmen would grab a big hammer and WHAM 'em once so metal distorted and they appeared seated.

This led to us calling the fasteners themselves "B96 nails"...
