The 8.8 refers to "property Class". The 8.8 is close to an American grade 5.
The KHS refers to the manufacturer. P.C. 10.9 is the first step in high
strength fasteners. In addition to the grade there are also choices for the
finish. As important if not more is the quality of any washers used. A good
bolt and nut does not matter if the washer deforms under load. Washers also
come in grades. Find a supplier that offers fastener systems (matched bolts,
nuts, washers). Lawson Metri-torqu is one of my favorites although the price
of their washers is scary. Their plating is fantastic, the bolt heads are
taller than normal, and the line is DIN spec so everything stays the same
wrench size as OEM.

Hi all.

I may need to use a longer than OEM cross bolt where the transmission front
mount bracket bolts to the bracket on the frame.

The bolt I removed has 8.8 grade mark and "K H S"

Longer bolt I'd like to use has what *looks like* 8.6 or 8G and "F II
S"   or  "F H S"

IF the second bolt is a grade 8 bolt, is it ok to use in place of the OEM
bolt?

Thanks,

Neil.
