T.P.I. stands for "Threads per Inch". AF stands for "across flats".
Bolt and screw lengths are measured under the head and the diameter is measured across the shank. Shorter lengths are usually supplied threaded all the way up, whilst longer lengths have part thread and part plain shank.
Hexagon bolts (excluding zinc and assortments) have the top face mirror polished to remove marks and lettering.
