The front pages of the Bentley Blue book have
referenced all the bolt sizes and torque requirements
for the bolts in specific components- for instance
Tranny bell housing to engine is just one example.
Armstrong shock to frame- bolt size and torque.
I hope this helps. I believe every bolt in the car
can be found in this reference section of Bentley.
I am fairly certain this information is correct.
One of the Experts will chime in if I've made a
another rookie blunder.

The most common sizes I used on my TR3, which would be pretty much the same for all the Triumphs are...
3/8"-24
5/16"-24
1/4"-28
As far as the McMaster part numbers, their website is very easy to use. Since their are so many style nuts that they offer, it would be best if you saw the various options they have and chose which you'd like.
Just start by entering "hex nuts" in the search box. Pick the style you want and enter the sizes and it will come up with the part numbers.
Having said all that, here are the numbers for grade 5 zinc plated nuts.
3/8"-24 ... 95462A515
5/16"-24... 95462A510
1/4"-28 ... 95462A505
Edit: If you want nylocs or a different grade, then you'll have to search around their site, but it is easy to use.

For a TR3, I'd say 1/4 NF is probably the most common, closely followed by 5/16 NF; but I haven't really tried to catalog them. Not too many of the larger sizes, at least not in standard nuts. Fair number of 3/8 NF Nyloc and castellated though, on the front & rear suspension; plus some 7/16 NF Nyloc and castellated.
The torque tables are useful; but don't list all the bolts/nuts.
MMC changes their part numbers from time to time, so I've never saved them. What's really frustrating is that what they carry also changes from time to time ... I bought a box of hardened flat washers that were almost the perfect size to use under cylinder head nuts (at a time when the big 3 didn't have them), but when I tried to buy a second box for friend, MMC didn't have them any more.
