Is there some reason I haven't seen these applied to head gasket/bolt/stud installation? These would be the ticket for what has otherwise been a hit and miss deal with everyone inventing their own torque proceedure.

Maybe I've just overlooked it. I don't know.

the next time I put a head on it's getting these.
 
I don't think I'd want silicone squireted all over my internals.....but that is an ingenous idea for other applications.
 
^ no way would you want to do that, good torque wrench and your golden, last thing I want to do is clean silicone off all my parts and have a mess like that.

They don't have to explode silicone.

The whole problem with a torque wrench is just that, it measures torque, which is a second hand depiction of the tension being placed on the fastener.

Granted it works.... this method is infinitely more accurate because it isn't subject to standing friction.

JMO I guess
 
Did you read the install instructions? It's an educated torque guess at best. I think I'll stick with my trusty torque wrench.

Thanks for sharing the info...I just don't think it's practical in our application.
 
Good luck on guessing with no torqure wrench on your first retorque with those.
 
I'd stick with the washers that come with the studs. Use the arp moly lube and a good torque wrench.

Actually I found them at 3 this morning after a discussion at work about fastener inconsistancy. I didn't get to read through it thoroughly.

And for the other post, If you were to retorque, run fllat washers on the first breakin, and then install those.


If nothing else, it has good info about stressing fasteners.


Edit: should have read the instructions. Would have been a better Idea if they only worked at a predetermined load. no guessing how much squirt you have or need. those in conjunction with a torquewrench (as they are actually supposed to be used) would be deadly accurate though. That way one fastener won't have a different loa compared to another.
