I think the bolts class, 4.8 ( should read 4.6) and 8.8 are British Standard
metric bolts. gr. 4.6 tensile strength is 195 kPa and the gr. 8.8 450 kPa.
The AISI 304 bolts are a regular American product under ASTM F593.
I hope this helps,

Does anyone know what the following designations are or where I can find a
reference to help me? These are for structural steel and anchor bolts:
CNR 10011-88 (A code reference, I believe)
FE 360 Steel - UNI 7070 (structural steel)
class 4.8 and class 8.8 - UNI 3470 bolts
AISI 304 steel threaded bars
I am specifically looking for typical yield stresses.
