Aaron,

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.
