View Full Version : The thread of the hood-mounted spare-tire mounting bolts?

I have a re-galvanized "pie-plate" for a spare hood (sorry, bonnet) for my '71 Series 2A. In order to have the bolt fit, the threads need to be chased out. So far, no one in any bolt-and-nut store seems to know what the thread is! I've kind of given up finding another bolt of the size except for the official platinum-plated ones at $20 each.
Any help would be swell.

1/2 BSF for the larger diameter bolts:

You might try McMaster-Carr.

They are UNF, so regular old 1/2-20 works fine.

Hmm, I have some 1/2"- 13's screwed into mine to fill the holes.

Hmm. If that were the case, I'm surprised that nobody in the bolt-and-nut stores mentioned in the OP could figure out this ultra-common thread spec.

My 109 has 2 factory hold-down thingys holding the spare to my pie plate mount; One uses a smaller diameter bolt with a smaller head, and the other one (the one that people maintain is 1/2 BSF), has a 1 1/16" hex head.

To the OP: Easy enough to tell what you have--Grab a thread gauge (or a ruler if you don't have a gauge) and check the pitch. 1/2 BSF has 16 threads-per-inch.

The heads match lug nut size so you can remove them with lug wrench. All the ones I recall have this larger head??

The thread for the "special bolt" changed in '58 and a different bolt was used. Unless the spare support plate is from a Series One, it should be the 1/2" BSF 16.

I use a breaker bar, extension and socket instead of a regular lug nut wrench. I also switched to a tire hold down from a Defender to get rid of the Series type clamps. When I upgraded to Wolf wheels the bolts for a Series wheel too short so I purchased threaded rod and loctited stainless steel acorn nuts to the rod and made my own hold down bolts. I did have to purchase the correct size socket too. I keep both sockets and an extension in my cubby box. I think I sold the bolts and clamps for the Series wheel for more than what I paid for the other parts that I had to buy.

After I went from 15 inch rims to my 16 inch rims, the bolts holding the tire on the bonnet were to short. My Land Rover is 1967 Station Wagon, made for the US market.

Here is the correct size and where I got them. Very High price due to shipping cost.
