To the guy with the long rant about torque and inspection, if that was all that was needed, you wouldn't have these Or safety wire

Gee, I didn't think I was ranting, this is a part of my work, and I lock wire regularly. Yes, I also use much more specialized locking and single use aviation fasteners, though consider them outside the scope of a discussion about lockwashers on a tractor forum. Suffice it to say that I don't suffer problems with fasteners coming undone on my tractor, and I want to share my successes if it will help someone else here....

Alcohol isn't the best for cleaning anything with real oil. I do keep some in stock but use paint thinner/actone when cleaning bolts for locking.

Carb cleaner would work fine.

I've read some of the horror stories here on TBN - about things falling off or apart. I put Blue Lok Tite on all the wheel nuts on my tractor. Also on the FEL nuts and on my rear blade main nut. I took no special precautions about wiping thing off. A shop rag was used. Subsequently - checking some of the tractor wheel nuts - the lok tite is working very well.

Sorry about that - spelled horror the wrong way.

If you have some oil or grease on the threads of the nut or stud, a locking product is of limited value.

I completely agree ArlyA. I was wiping off mud and dirt.

Locking all depends on the application and location as well as the size. You can use everything from threadlockers to Castellated nuts and cross drilled bolts to safety wire to spot welding the nut on... Just depends on the application.

Not a one size fits all scenario at all.

I have never had a ny-lock nut come loose. I saw the video showing a ny-lock rotating loose, but we do not know all the facts about the test. The demonstration was to sell their product.

Not convinced.

Nylocks are a single use item. Required a cotter pin in flight controls on atleast the airframe I worked on

I think a lot of folks viewing the video may have mis-understood it. And that is in large part the fault of Nord-Lock. In the video the fasteners are exposed to very high amplitude vibrations. These types of vibrations can and will loosen most types of mechanical locking methods. But most fasteners are not exposed to the type of torture in the video. And we have all observed this. Most of the time our fasteners stay tight. Sometimes we will come across a bolt or nut that will not stay tight, but this doesn't happen often. It was interesting that the video did not show the efficacy anaerobic thread locking compounds. But then it was only showing mechanical methods. Anyway, in over 35 years of using Loctite anaerobic thread and other locking compounds I have NEVER had a joint fail when the locking compound was used properly. This means the proper metals, completely clean parts, proper temperature range, and proper compound. I have a lot of faith in Loctite products, but they need to be used properly.

Consider Aviation practice.

"Lock washers" are for non critical applications such as instrument mounting or cable guides.

Nylock nuts are used (one time) for general application.

Tie wire castellated nuts and drilled bolts are used in flight safety applications

"Jet nuts", all metal deformed thread, nuts are used in elevated temperature applications.

Add the numerous "specials" and you have quite a selection.

I've not seen liquid "thread lockers" called out , but I've been out of the loop for some time.

I use red loc-tite around the shop ;-)

PS

I've never had a well snugged lug nut come loose on any vehicle I've ever owned over the past 50 years. Something to be said for tapered seats ;-)
