Ya, you're right Larry, it was an automotive reference.




Oh wait a sec, here is the exact sticker on "my" trailer which has 1/2" 20 studs. Well would you look at that!!! The EXACT SAME torque value that the "non germane automotive reference" I posted has. :W

This basically meaningless statement IMO just PROVES what I said about you not understanding. Just because what you posted happened to also include some of the range of torque values for trailers STILL DOESN'T change whether your initial information was or was not germane to the topic being discussed. The fact that what you showed is for some yet unknown trailer, maybe a single axle ???? just happens to include what your original automotive reference had means something just further IMO still clearly shows that ... YOU STILL DON'T SEEM TO UNDERSTAND:h:S


And we all know that trailer manufactures use the very best parts money can buy, including aero/space quality fasteners to hold the wheels on don't we? :B After all, look at the aero/space quality frames that Lipert makes. :B

AGAIN a totally useless and non germane comment aimed at somehow used to apparantly cover your lack of understanding even what I was saying. Often WA statements like this are made when one is either caught with their pants down or not wearing them at all in a conversation, so I can only assume this bolsters my original comments on your post IMO :p

By the way, you're incorrect about higher torque specs on wheel fasteners just because they are mounted on trailers. "Any given fastener" has a yield point. It doesn't mater if that fastener is on a
trailer or a car or a wheel barrel; it has a yield point and you better not exceed that yield point. Now some applications may use a better quality fastener because that is what the engineering spec calls for. But you just can't crank down more on a stud just because it's mounted on a trailer. Or at least you shouldn't.

A third example of you not understanding. I only said IMO higher values were because of the somewhat unique things trailer wheels might be subject to. More than just one reference for trailer wheels appear to include the MAX TORQUE number for the size, grade stud/nut for trailers, something to my knowledge many automotive manufacturers do not do. I in no way implied what I said was a FACT it was only my opinion and while that might not be shared by others one's opinion can't really be incorrect or wrong ... IT'S JUST THAT AN OPINION;) You can agree or disagree with it, but trying to say it's incorrect or wrong is meaningless IMO. That's sort of like one having an opinion that there is say a HEAVEN and someone else saying that opinion is WRONG OR INCORRECT. Same goes here IMO



One things for sure, one of four things happened:
#1. The fasteners were defective.
#2. The fasteners were pushed past their yield point by over tightening.
#3. The fasteners weren't preloaded enough by under tightening.
#4. The fasteners were pushed into an overload situation and failed.

OP, take your pick on the above. It's all a guess which one happened without forensic analysis on the studs.

See again a FOURTH instance showing at least me you really DO NOT UNDERSTAND. You IMO make a statement of fact, but failed to include probably the most common problem that could lead to the failure here and that being not checking the torque values after initial CORRECT TIGHENING to PROPER TORQUE VALUES multiple times over a very short time frame mileage wise to ensure they had not become loose.

This isn't my first rodeo Larry. With only 4 bolts holding the whole front end of my race car on, I better know fasteners or I'm a dead man. :E

Of course we have no idea how safe of a race car driver if you even race are nor how many fastening failures your race car has had. We only know that AS OF THIS POINT IN TIME you seem to still be ALIVE, NOTHING ELSE is gleaned from this IMO useless statement. I guess you could also be DEAD from a race car fastener failure and someone else has gotten your RV.NET info and is posting in your name;):E AGAIN another NON GERMANE comment thrown haphazardly thrown in to bolster some position that only you seem to know what it is.
