Does torque spec change with SS allen head bolts?

(1/2) > >>

Hey all

I ordered stainless steel allen head bolts for my engine job, and just wondered if the torque spec changes when using them. I am using nickel grease with every single one of them.

Also, what's the take on following the torque specs in general? I see most people recommend following torque spec with bottom end and head, and then just recommending hand tight with all the covers and the rest.

What do you think?

Torque for ends, mains, head and rotor. Sensible tight for the rest BUT i am talking doing it for 40 yrs sensible!

What about "never-having-done-this-before" sensible? How does that feel? 😂

Is it advisable to Loctite the rotor bolt?

Sesman:
As a very basic rule, 6mm is 6ftlb, 8mm is 8ftlb. Again as a basic rule and doesn’t apply to high load critical fixings or high tensile etc. nip it up and another 1/8th turn. Again, it’s just a feel thing.

A second engineer i sailed with told me "till it snaps and back half a turn" got really peed off with me when i did a flange joint with 3/8 bsf like that
