MG TD TF 1500 - BA Threads

I am finding a number of BA thread screws and studs on the TD.

I don't have the original screws used to hold the Guarantee, Patent and Body plates. Can someone tell me the length and primary width? I would also like the size/type of the nuts.

I also found the packing ring on the steering column is BA. The thread measures out at 0.23, or 0 BA. But the nut takes a 3 BA wrench.

So when reporting BA thread, do you list both the screw size and the wrench size?
Bruce Cunha

I can't answer your question Bruce but I can confirm that when restoring the TC and TD ignition switches I found that the nut at the rear that secures the lock body extension has a 4 BA thread but a 6 BA spanner is required to remove the nut. I haven't been able to find these odd sized nuts anywhere. Cheers

Anything BA I look at British Tools and Fasteners here in NY, of course they will be standard BA sizes.

Sorry for invading your post Bruce, but speaking of screws, what size screws does the distributor fixing plate take to secure the points? PJ
PJ Jennings

I will have to leave that one to someone else PJ. I was not doing the motor on my list.

I don't see it on the late Dave DuBois engine list. An email to Jeff Schlemmer at Advance Distributors may get the answer.

Thank Peter. That is what I am thinking. Unless someone has more information, I will list the Thread as the BA size by the diameter of the thread and the wrench as the one that fits the nut.
