Grease your nuts?

    It's not the hull, but it transports the hull, so what the hay.
    Someone has to get a first post in this section done.
    Spent a half hour web-wandering in search of an answer.
    Answers were split 50-50 pro and con.
    Got my trailer today, new, so before anything corrodes
    I'm getting in a little preventative maintenance.
    Boeshield on assorted nuts and bolts, clips, springs.
    Got to thinking twice about the lug nuts.
    They are torqued fasteners, and so...
    do you grease your nuts or keep them dry?

    Just try to keep a straight face when you answer this question
    I couldn't and I'm the one asking...

    I prefer them dry.  In the years of towing trailers, granted not as long as some others, we never had a failure.  Hubs are not that expensive & much cheaper than having the nuts back off @ 60.

    I'm not very funny, you got off easy!

    That's a myth! They don't just fall off @ 60 ::) (or so I'm told :p)

    I grease em. ;)

    That is true CR, but when you are like me and forget to check things like that on a regular basis...

    I've been reading my way through tech sites, it seems the problem
    is not that the lugs will spin off while towing, but that lube on the
    threads of the stud will cause over torquing when tightening the
    lug nut. Torque specs are established for clean dry threads.
    So adding lube changes the way that force is applied to the studs,
    and that a false low reading will show on the torque wrench.
    A few sites recommend a high temp thread anti-seize like that
    used on spark plug threads. Others say marine wheel bearing
    grease applied sparingly is the way to go. Others say absolutely no
    lube of any sort. So, do you lube your nuts, and how many of you
    torque your nuts?

    I'm lmao, and it's a serious question... ;D

    Well, I have had friends have lugs come lose on car wheels so I always made sure mine were tight.

    Truth is, I use a Snap On cordless impact. I know it's not to "spec" but every used trailer I buy, it's the only thing that will break them free. ::) I've spent a few years bust'n nuts so I'm pretty good at putting them back on without over-torquing and/or stripping.

    Here's the real deal. Grease the threads to prevent them from seizing. DO NOT grease the cone mounting surface of the nut or the compression mating surface of teh wheel. This is where you affect the way the compression of wheel and subsequently how tight it gets. If you grease this part, the nut will get tighter than it needs to be, and once that grease isn't new and slick anymore, that super-tightened nut will really not want to come off!

    I pull the wheels, and with rubber gloves on, rub a thin film of grease over teh entire hub and studs. I also like to put grease on anything I don't want to rust, all nuts, bolts, u-bolts, springs, especially the springs, axle, etc. Then put back on the clean rims and lug nuts, and go fishing.

    Oh, and I never put my trailer in the water, only the tires, and even those not even up to the rim. Keeps it new indefinitely. I recently sold my stumpnocker with a 16 year old Gator trailer under it, and it only had rust on the very rearmost crossmember where it would tough the water while loading. The rest looked new.

    Wow that was long winded!

    With all that typing...
    It's a wonder you didn't drop one of your greasy nuts... ::)

    Thanks for your input Brian, I'm gonna grease my nuts...
    then torque 'em, and hope I don't bust a nut doin' it.
    just not right now.


    This has been a seriously funny post,
    and I'm so easily entertained.

    If threads are clean, grease them after you torque them to keep them from rusting.  If properly torqued, the thread where the nut is won't be exposed to the elements.  I have used a torque wrench enough times that on something the size of trailer lug nuts that I don't bother with the torque wrench anymore.  I have developed a certain feel for my nuts.  A properly maintained bearing in a hub on a trailer without brakes will not get hot enough to seize the nuts, even if they are greased.  On a trailer with brakes, the hubs can get hot enough to fry the grease and seize the nuts, even if properly torqued.  If you do use grease, make sure it is a "moly" type.  Better yet, use Moly-Kote, which comes in a spray can and is used on all parts that are stressed and subject to high heat.  I wouldn't think of rebuilding any engine without spraying moly-kote on all the bearings, journals, cylinders and rings during assembly.  Amazing stuff.

     (moly:  molybdenum disulfide)

    Gramps, are you saying you don't take care of your nuts?
    Or are you saying that you forget that you have them?


    Thanks Kemo, I forgot all about moly spray,
    there's a can in the garage, somewhere...
    I'll spray a bit on my nuts.


    Kemo, how big was your grin when you typed your reply?
    Mines running ear to ear....

    I usually grimace when I type.  But when I proof read it I almos laughed out loud.

    That is what my fishin buddy is for!  ;D

    Seriously though, to help with corrosion overall I spray "Pam" cooking spray on the trailer, hubs, axles, etc.  Does a good job of keeping the salt water off, cleans easily & best of all cheap.

    You'd have to be careful getting off a too tight nut.
    You could hurt yourself applying too much torque.
    Why is this so funny?
    It's a serious question, vehicle safety is at stake.
    We should be worried about the condition of our nuts.
    Rusty nuts don't come off!
    Too loose and you can lose them!
    Grease 'em and you can twist them too hard!
    Nuts that are too tight can break!
    Everything rides on the condition of our nuts!
    Our nuts are what holds things together!
    Quit laughing, this is serious....

    Maybe we should write to the makers of Pam, they might like to somehow add nuts to their ad campaign.

    I was using Loctite rust preventer, it's a spray oil. It really hasn't worked real well so this thread is good.

    PS, I might change my screen name to "Rusty Nuts"

    I pulled my nuts off when they (the trailer) were new.  I lubed the threads only with anti-sieze (because you want to get them off at some point) and slap them back on.  I make sure to check the torque on them every time I check the pressure (tire)or grease up (my hubs).  I spray a nice mixture of special spooge all over the trailer to keep the rust off too.  

    Twist this as much as you want.   :cool:

    Un-shore (aka Rusty Nuts) thinks he's been set up.
    No way, Rusty. A set up would require malice
    and forethought. No malice or forethought here.
    Just a little holiday cheer. Lug nuts roasting on an open fire,
    or something like that. Over the river and down I-4 to the ICW we go.
    No that's not right either. Dang moly spray is a little thick in here.
    Nope, the only thing going on here is a serious question, that some
    people have taken a perverse delight in twisting to their own wicked ends.
    I'm just the owner of a well developed sense of the absurd.
    I like seeing the humor in day to day life. I hope others enjoy
    seeing the world from my point of view when I point out the silliness
    that is out there. I've taken care of my nuts, and will continue
    to do so on a regular basis. Frequent inspection of your nuts prevents
    failure at inopportune times. Grease 'em or not, check them often.
    You don't want your nuts to seize up at an inopportune moment.
    Like most things on boats...inspection...detection...prevention!

    Matt, flyfishrmn82,
    Ya'll are making me snort my coffee.
    My eyes are watering from laughing,
    and laughing is as good as fishin'!

    This is great!  What started as a serious talk about nuts and to grease or not to grease has evolved into a compilation of nut care tricks, the birth of some questionable nicknames, new uses for cooking spray, and what appears to be Brett's first few pulls on the season's first batch of egg nog!  

    You know what I'm thankful for?  Good, quality entertainment with good hearted folks.  Happy Thanksgiving.

    Oh, and Brett, you want to be sure you can always get your nuts off when you need to.  You don't want to be stuck on the side of the road, middle of the night, mid-January, and you can't get your nuts off on your trailer.  Makes for a long night.   ;D
