Propeller shaft bolts and nuts

[racerken]

Hi,

I just replaced u-joints on front and rear shafts and now have to decide between dealership nuts/bolts vs. Mcmaster carr, etc.

The factory bolt is M10 x 1.25 x 25mm and the nut is a flanged nut. The bolt + nut is about $5 per set and I need 16!

McMaster lists a grade 5 & class 8.8 with the tensile strength of 116psi @ $11.25 per 25 units.

Will this do? I guess the real question is what grade or class is the factory stuff made of?

BTW, the torque for these bolts are 44 ft-lbs so it can't be that hard??? (dunno)

Thanks,

Ken
