1960 castor screw thread

[felipevsw]

I have this JCM 900 Lead 1960 A cab that I bought used without castors.

I know they have these feet with slots that you can screw castors in, but I'm wondering what's the thread of these slots in the feet...

I can't get original castors where I live, but there are some other "office" parts that should be similar. These office castors come with a 3/8" screw.

Anyone know if the 3/8" screw would fit in the original Marshall feet?

Depends on when the cab was manufactured.
Best bet is to try some bolts in the sockets first.
I had some that were metric M10-25, but I believe there are also versions that are 3/8-16.

M10 threads on my newer Marshall cab.

My '71 1960 has a thread that's similar to 3/8" UNC.

This one cab is from 1995, according to speaker codes.

Remove one of the sockets and take it to a local hardware store.
Try a few different bolts and find out what thread size you need.

I'm gonna do that. Thanks.

So it is indeed M10.

I removed the socket and went to the hardware store to test some screws.
