From STORMCAT - "The other nice thing about the Accufab kit is the outer 6 bolts are reusable. The Ford bolts are one time use."
Hey Brian, as I have said many times the Accufab kit is fine and currently the best fix for those wanting insurance their car will not succumb to a premature axle bolt failure. There is NOTHING wrong with Torque-to-Yield (TTY) bolts and actually they probably provide more consistent clamp load per tightening method than strictly torqued bolts.
Other than you have to "throw them away" after each use (which from an engineering stand point you really do not have to do-after ONE use) they are perfectly fine. And in fact there was a considerable engineering effort expended on this bolt flange (this is Ford's flange not Riccardo's) to come up with the TTY application. Many aerospace load-sensitive clamping operations where precision clamploads are necessary are routinely specified as nut-angle-turn or TTY tighening routines.
I for one am driving my car and will have the new Ford CA kit installed when it becomes available.
