Are these original early 42 GPW hood block screws/bolts?

Post by lowbonnet » Sat Jun 24, 2017 10:51 pm

I have what I think are three original slotted bolts to attach the early rubber hood blocks to the hood/bonnet. One is broken, only the head. I find the bolt strange because the ring is fixed against slotted bolt. Anyone have info on this type of screw? The head is rounded and slotted. Is it correct for hood blocks of this early, 1942, type?

As long as I have my jeep, for 16 years) I never came across info about this subject.

Here is a photo of someone else's hood block which seems to have the same type of bolt:

Mine looked identical to those bolts on an early Marines jeep hood I had. I assumed it was a marines jeep due to the heavy bitumen coating on the underside that peeled off. My hood blocks were in worse shape though than the ones in your picture but were definitely original....they were very cracked, bleached and crazed.

Are your bolts quite longer than necessary and are partially tapered/pointy at the thread end of the bolt?

My March 42 GPW has identical screws and washers. I have photos but can't post off my iPhone. I need to log on to my computer.

Thanks for the response, would be nice to see some additional photo's. These rubber blocks are reproduction, but I have the original and another original pair and the originals seem to be thicker. I will post a picture of them later today.
Ah, I found some more info on the differences in thickness: viewtopic.php?f=69&t=210393

This early 2nd contract GPW is very close to my June 42 and has what seems the thicker version of the hood blocks as used by Ford. Anybody know a source for the hood block bolts?

Is that a round muffler?

I thought that Ian would have seen this thread and posted. He's the man for fasteners :D I wouldn't mind a set for my June 42.

Interesting screws. In my opinion, the screws in the unrestored photo in post 1 are a replacement roundhead with washer underneath, and a flat panhead style with a washer underneath. I've never seen anything on a GPW with the ones in top of the 1st post. All I have seen are a flat panhead style with a separate washer underneath. Interesting.

The interesting thing is that the slotted screw has the ring fixed to it, it is one unit, and it fits perfectly in the used rubber blocks that I had which had a stamping/marking in the rubber of a previous screw with ring. The ring of my screw fits straight in.

My Apr 42 jeep hood blocks, original rubber, had screws exactly like yours with what appeared to be a washer machined as part of the screw. They seemed to be a solid part of the screw. However, when wire wheeling the screws to remove rust, the washer separated from the screw. My theory is that the washer was assembled to the screw while paint or primer was still wet causing the parts to dry very tightly together. I think you will find the same if you wire wheel yours.

I’ve seen similar screws with the washer being part of the screw on terminal strips and other locations to terminate wires.
I believe they would still be available.

Isn’t an M6 x 16 mm a metric screw? Also, seems to me it would be too short. Anyway, as posted above, I believe those are separate (SAE) screws and washers.

I know it is too short and I know m6 is not correct. All I wanted is to refer to is to this type of bolt and the head and ring are for 100% NOT separated; mine are fixed to each other and it appears that they are still being made today, and Frankie you can stop now being stubborn.
They seems to be called "Washer Head Screws", only I haven't found the correct length yet. And like some other posters, they have the same on their early GPW.
