Door top to door bottom bolts

What is on the other end of these bolts (inside the hollow section) as shown in the photo.

As you can see, they are quite a mess with rust. I was planning to simply grind off the welds, and replace them with some fresh bolts.

However, there doesn't seem to be any way to get inside the hollow section. What I would like to know is whether there is bolt heads inside the hollow section.

Thanks for any replies.

There are no bolt heads, that is simply a stud welded to the bottom frame of the door top.
Best option would either be to cut off and replace, or recut the thread with a die and grease it well!

Yeah, 7/16" UNF from memory.

Thanks for the replies. I bought some new 7/16" UNF x 4" bolts to replace these. I probably could get away with running a die down the threads and cleaning the rest up with a flap disc.

OR just buy two new door tops ....£50 each fully glazed ....or £30 odd a pair unglazed ....

You'll be replacing the ones you have shortly anyway ....plugs/points/filters and a brace of new door tops please ...

unless you buy Wolf all alloy ones they are a service item .

Where do you get door tops at 30 quid a pair?

Thanks, thats where mine came from but I forgot that I had bought ther runners for the glass and there is also the carriage.

I have to say that on first inspection they look very well made.
