Indeed an interesting topic, there must have been huge quantities of surplus threaded components available post WW2 both ours and yank stuff, so clearly made economic sense to use this whenever feasible..

Hells teeth.....thought I'd have a quick Google to see if it was any easier 2 years on. Certainly found some, but 75p each !!

compared to 6p for cheese head?

What gives?

You may find that 2BA purchased from your favorite LR parts suppliers under their part number are more reasonable.

Also 5mm panheads are very cheap and no problem if they are for a through bolting application.

Must have changed nearly 500 fixing on my suffix c S2a, for stainless in most cases. The only (1/4") UNC thread I found was holding the front of apron onto tapped hole in chassis. Not to say there aren't others of course.

Re the 2ba screws for the dashboard

The ones I used were branded 'Britpart'. You could tap them out to M5 - a couple of the threads on my clutch pedal box were stripped, so were tapped out.

I used Namrick metric stainless pan heads where practicable.

Just to add one more, the "special" bolts that hold the spare tire on the bonnet. The heads are 15/16" to fit the wheel brace until the S3's(?) then it went to 1-1/8" along with the wheel lug nuts.  I don't remember the thread size, I've got it somewhere.....

1-1/8" or 1-1/16"? My 1970 S2A has a full set of wheelnuts for which I need a 27mm socket except for one "odd" 15/16" one. 1-1/16" = 26.9875mm so near as dammit for the socket fit.

I've been told that these 1-1/16" (27mm?) nuts with the same stud thread as the normal 15/16" ones are only found at hen's dentists or behind incontinent rocking horses. Can anyone help with one? It would be nice to have a full set!

That looks like it!  Thanks for the pointer.

One for £0.26 sounds good, but one for £5.26 (inc shipping) might have to wait a bit.

Is 9/16" the stud diameter of your vehicle?

Regards.

[Herald1360]

Yes. It's the same thread as the earlier 15/16" AF wheelnuts.
