French Lock question
IS there a secret to installing and torquing these to 75-80 ft/lbs without ripping them? I used new Gr 8 fully threaded bolts and ripped them, tightened them evenly and ripped them, applied never-seize to the bolt heads and ripped them, used a couple of the original bolts with the shoulder and one lock DIDN'T rip the other did!They all started to rip around 50 ft/lbs.
Is there a reason why lock washers can't be used instead,why were the french locks used to begin with?

Chuck the Frenchies, and use blue loctite. Be sure to clean the anti-sieze off both the bolt threads and the hole threads (spray with brake clean). Loctite also sells a primer which they recommend using with all their locking products.

74 Thanks,
I was thinking aboutusing the loctite but want to know why Gm used the these lock to begin with and why a lock washer couldn't be used?
