One of the rarest items to find on current long wheeled base CCKW's are the original lug nuts that go on the spare tire carrier. They look like the regular wheel nuts but have no outside threads on them for the large wheel nut.

Hey, thanks for the info. I had never noticed that the lug nuts had no threads. Only had the spare off once but mine has both of the originals.

You are lucky OD. In fact the carriers themselves are pretty scarce unless you find a truck returned from Europe. Trucks that were de-militariszed here in the states normally had the spare tire carrier removed and thrown away.

So that's what this is! I thought someone was just having a bad day at the factory!

Ws, when you think about it there are probably still thousands of WWII/Korean War vis that there is a new generation of CCKW collectors that are gaining their education on their trucks from other new collectors mainly via the internet and not the publications, this item is described in the CCKW parts manuals starting with the TM10 Series. The Master Cylinder Inspection Plug in the floorboard of the Closed/open Cab CCKW is also ver ears that was not GM or US Army issue, they are quite different in appearance.

and a nut was tightened onto the spare wheel carrier to frame stud which kept the spare securely locked in place so that it would stay put during whatever rough use the truck was put thru.

Part of the Wheeled Vehicle Testing program at Camp/Ft Holibird, Detroit Arsenal, and at Aberdeen Proving Ground was to ensure that the components and accessories of combat vehicles be secure and d

I wonder if all those CCKW owners that spent $400.00 for Spare Tire Brackets have them happily installed on their CCKWs?

I was watching a GM film over the weekend that show-cased GM's efficiency in war production - they substituted a lot of innovation for old fashioned manufacturing methods - instead of some forgings they used an alloy called armour-steel (not armour plate) which had the requisite hardness but could still be machined and powdered iron which was moulded dry into shape and then heated to form a solid part.

I guess the spare tyre nuts are lug nut blanks that never had the final outside thread machined on them - GM was big on saving time and money in production. They then had to create a separate inventory line and print different packaging which lessened the savings somewhat.

This efficiency drive probably explains the many changes of parts like the hydrovac - the early ones weren't necessarily defective just that later models could be made cheaper and quicker.
