I just torqued mine down per the manual at 12 lb ft and 3 of them stripped. I'm beyond mad at this point.... I'm guessing that means I need a new chaincase?
 

Depending on location you could drill them out and use a bolt

too late now but I run a die over all the bolts and tap the holes to clean out the loctite. Having old loctite in them when re tightening makes it tough to feel the threads. It’s delicate work. Sorry to hear the threads gave out

UPDATE: I used my snap on tap and die set to clean out all the threads. I replaced the damaged screws and put it all back together and got everything torqued down to 10 lb ft..... I didn't dare go to 12.... What's everyone's thoughts on that? Hope that's ok. 12 seems like a lot for these screws.
 
I dont torque the chaincase bolts, just do it by feel. I have heard of a few people stripping them at 12 ft lbs.

I'm wth Big_Phil. Set my expensive digital torque wrench on 10lb. and broke the screw. Must stretch when retightening every year. Got it extracted but a bit of a pia. New screws and and went by feel.
 
Just did mine today third time it’s been apart 12 ft # on a snap on 3/8 drive no problems
 
I always use an inch lb torque wrench for anything 20 lbs and under! They are more accurate imo
 
I broke 1 screw yesterday at 12 ft lbs. and felt another one start to yield. Luckily I was able to get the broken screw out easily.

I will either go to cap screws or torque by feel. Very discouraged also.

Yes, I was using an IN LB torque wrench.... Just did the conversion from LB FT to IN LB.
I've broke two heads off and was fortunate to have to have enoough thread to back them out. Have to make sure both threads are absolutely dry and void of any oil or they will easily strip. I also agree with the inch pounds torque setting and set it at 138 inch pounds (11-1/2 foot pounds) and check "hand-tight" after and then again after first ride.
 
What's everyone's thoughts about using blue locktite and only torquing to 8 ft lbs?

I have stretched the screws before at 12 ft-lbs, I have now done several cases with an in-lbs and dont go over or 100 in-lbs. You can see the cover is seated metal to metal on the flanges so going over is a waste and a little blue loctite will not hurt.
