I have seen fastener kits for type 1 Beetles but nothing for the Thing.
I spent a part of the weekend on my back with a sore back, so I used the time to go through the 181 parts book and list all the sizes of bolts and nuts in the 181 .
I did not include certain types of carb screws and cheese head screws, just all the nuts, bolts and washers with quantities.

This should give the user a good idea of what's required to build a Thing and what to have in a spare parts kit for a trip.

Hope to have it soon, will send it to Everett as a .doc file, he can do with it what he thinks is in the best interest of the Samba.

I am sure there are going to be a couple oversights, just send those to him to make a better product for us all.

I sent the completed document to the webmaster for inclusion in the Tech section or wherever he chooses.

Now I have to finish the VW 181 Bundeswehr manual!

Got 40 pages to go.

Now to document where each of these bolts and nuts are used.

Thanks for the list, its going to make ordering/buying hardware a lot easier!

There are also a lot of metric flat washers and lock washers . Most of the nuts and bolts are available there are a few that are not the bolts that hold the front and rear backing plates are special because you can't get the bolts with the correct head size also the bolts that hold the rear torsion caps same problem also the bolts that hold the rear body bolts and you have to have the right size heads on the bolts to get a socket or a wrench on them

Thank you for doing this. Awesome job and I appreciate the time it took.

But as a side note, I thought the threads on a metric bolt was defined by thread pitch and not like an SAE count of threads.

As an example for SAE it would be 1/4 20. Or 1/4 diameter bolt and 20 threads per inch.

The metric bolt is defined As M12 1.5 or 12 mm diameter and 1.5 threads per (I do not know the measurement for the pitch, I just know the thread pitch).

Right so all this hardware is 1.5 thread. The second number is the length of the threaded section in Millimeters. So an M6x30 is 30 millimeters long.

The Things use a few different threads 12 mm x 1.50, 10 mm x 1.5, 10 mm x 1.25, 8mm x 1.25 , 6mm x 1.00 Metric bolts are not like USA threads most of them come in 3 thread sizes 1.00, 1.25, 1.50 except when you get in the small sizes the 3,4,5 but most of the thing bolts are 1.00, 1.25 or 1.50 maybe this will help also they don't use the wrench size like USA does the wrench size is not the size of the bolt you can get a 8mm bolt in a 10mm, 12mm, 13mm, 14mm wrench size. Also you need to watch the hardness on the bolts most or 8.8 but some are 10.1

Well, I'm glad we had this discussion, it shows that Thing owners are smarter than the average bear! I did this as a short cut.

It's true -- SAE typically calls the two types of bolt for each fastener size-- "coarse" and "fine." This is partly a designation from other industries, but pretty much turned out to be true in general practice.

Example:

A 1/4 inch bolt can be 1/4-20 (coarse thread) or 1/4-28 (finer thread). With almost no exceptions this two-size combination is true.

In the case of the metric threads, the coarse and fine designations break down almost always to 1.00 mm threads (for fine threads) and 1.25 or 1.50mm threads (for so-called coarse threads) until you get to really big fasteners like 18mm.

If you want to see what I mean, wikipedia has a chart here:

http://en.wikipedia.org/wiki/ISO_metric_screw_thread

One of the few exceptions in reality is the thread for the Citroen hydropneumatic suspension system, which had to be tighter.

It is a 36mm thread. But fine thread at 36mm is 3.00 mm, but that's too loose for the Citroen system, so they specified a 36mm x 1.25mm thread on the 5 million DS -IS -SM-CX-BX-XM cars they made from 1955-1992.

You are right.
Somebody at VW goofed when they were doing the packaging engineering, and didn't realize you could not do certain assembly operations out of sequence, because you could not reach certain bolts!

I would be tempted to just buy 100+ locak washers and flat washers for the key dimnensions: 6mm 8mm 10mm then use them as needed.

I did notice a couple of lock nuts specified on the Thing, as well, but I forgot to note them.

Strelnik is right the best way is to buy the hardware is in bulk that way you have what you need you can save a lot of time. Nothing like putting a thing together and you have to run and pick up a washer and you loose a hour of your time . We are putting another Thing together and I just got a few more nuts and bolts I was running low . Make sure you allow enough money for hardware just this much was 125.00. The Domeck Brothers replace all the hardware when we build a thing it just makes the job look right and it is a lot easier and takes a lot less time.

Correct! the thread would be M6 x 1.50mm x 30mm length

I stand corrected. The 6mm appears to be one of the few thread sizes that does not have a fine and coarse version.
