UNF strength grades.
I'm not fully up to speed on this, but there appear to be 2 systems for giving this information.
UNF bolts used on British cars of the 60's and 70's were stamped with either: R, S, T, or X. These being inceasing values of either yeild
or UTS figures in tons/ square inch. I think R was 45/55, S 50/60 and T 55/65 from memory.
There is another, more current system which uses different numbers of radial lines stamped on the head.
This site here gives more detail.

I have the best grade Aerospace NAS bolts available from stock for not much more than commercial stuff.
The info I'll need from you will be the diameter which I guess is 3/8 and the distance between the outer edges of the bracket you are bolting
through.
These are 95.000 psi in shear and 160,000 psi in tension without the brittleness of industrial 12.9 grade stuff.

Tell them about the bent treacle edges!

You Dutch-India 
We don't want them back. First let us clean up the mess in Europe.
But I still think you should get that EURO-coin! And drive on the right side of the road

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Bolts
Aerospace bolts are the way to go for suspension etc. You know they are high quality, are plated and available in the correct length without having to
cut a load of thread off.
