idiots guide to fixing sizes
so, this is probably a very large topic, and I probably should just buy a book, in which case, recommend me a book!
but we have metric bolts, which have different tensile "strengths"? which are then graded by letters? which are stamped on the head of the
bolt.
and we have imperial sizes, with the same idea i guess.
to top it off we have different thread widths, and I believe I am right in thinking if you cross reference the thread width with the thread diameter,
we have a table of torques in n/m or lb/ft which Mrwibble can use as a guide to torquing up the suspension bolts on his car.
so in summary,
what do the symbols on the heads of the bolts mean. and does anyone have a good link to a table of torque values for both metric and imperial fixings
commonly found in automotive use.
ta.

B&Q fastenings have no place on a car, use 8.8 as a standard and you will not go far wrong.
Column 2, 5 from bottom.

If you want a good book (bit American) that goes into the theory of fasteners then you could do worse than this:
Linky
aka "Screw to Win" based on the other books he's written.
