MG TD TF 1500 - TF Chassis & Fender Bolts?

Are chassis and fender bolts on the TFs BSF? PJ

Most are 5/16 BSF with a few 3/8 BSF used for the fender tiebar brackets.

That for the front fenders. I thought I saw "front" in your post. My rear fenders were aytpical bacause my car no longer has captive nuts in the rear. Not sure what came from the factory, but I used 5/16 BSF in the rear too.

Tom,

Rear Guard setscrews on a TF were originally 1/4" BSF.
The manufacturer of these was 'Rubery Owen' on this part of the car.

Thanks for confirming they are BSF. I have the original tie bar bolts, but that's about all. Been so long since I tore this thing apart, I didn't remember the rear fender bolts were 1/4 inch. Thanks Rob for that info. PJ

Paul,

For another bit of TF trivia,the four(4)setscrews which affix the bottom run of the side engine panel to the chassis frame were,from my experience, originally 5/16" BSF,'Sparts' manufacturer.The washers here are smaller diameter(1") I think compared to the larger diameter washers for the rear guards.And so it goes on...................!

Thanks Rob, I'm sure getting an education on these cars.
Incidentally, I save every bit of info you guys give me for a later date. Can't thank you guys enough for all your kindness and your relentless efforts to help. PJ.

My cowl carriage bolts have R504 in raised letters on the outer head surface and appear to be 1/4 inch bolts, is this correct? What threads are they supposed to have? Seems like the nuts are standard threads. PJ

I meant to post this here, instead of the other thread.

They are British Standard Fine (BSF) as are all the chassis bolts and screws larger than 3/16 dia. Most are 5/16 BSF, some 1/4 and a few 3/8

Smaller screws are BA, with 2BA being the most common. Carbs are all BA, ( 2BA and 4BA).
There is one "Whitworth" bolt (BSW) on the generator adjust bracket.

The engine and transmission are French Standard Metric (NOT ISO Metric), with Whitworth heads: 5 x 0.75 mm, 6 x 1.0 mm, 8 x 1.0 mm, 10 x 1.5 mm and 12 x 1.5 mm. reflecting their being built in the Hotchkiss Machine Gun Factory.

Late TDs and TFs rear axles have Unified Threads instead of BSF, these are the same as ANF ( American National Fine or SAE threads)

No matter what you may find on your T car, originally it was BSF, BA or FSM with Whitworth heads
