Hi folks What is the going torque for lug nuts for an EZ loader roller type trailer 5 lug<br />single axle. I wasn,t sure and didn't want to break any off so I torqued to 65 ft lbs. The left side tire came right off ,went rolling by me to take the checkered flag and I was left dragging as-. And all this in less than 3 miles. I was in total shock but thankfully no one was hurt and the road was real busy. Torque 'em and retorque 'em. and then torque them again. Thanks Boatz

Re: lug nuts torque

Whatever you torque them to make sure that you have a lug nut wrench in the truck that will loosen them.

Re: lug nuts torque

I Always torque them as Tight as I can comfortably Snugg them with a 1/2" Ratchet..........<br />My Calibrated Elbow would say about 65/85ft.lbs........<br /><br />I had that Same Thing happen years ago when I lived in NYC......<br />Bought a project boat over the bar down there,+ was able to restore the hull,+ trailer at the wharehouse I was at,..... 1958 Duracraft,.. Plywood on hardwood framed cutty cabin....196something JonRude on it, Gas Hog, V4,.... Cool old boat......<br />Anyway,... After the trailer overhaul,.. I was towing the package back up here to the Northcountry,........ It was abit Over your 3 miles,.. But the Tire passed Me,...... It used Lug Bolts, instead of Nuts,+ They Were Gone.........<br />Well,... Being Bondo,.. I had the old hubs stashed(I Think with All the Stuff, it might have been Heavy as well) in the boat,+ remounted the "Lost Tire".... Had to stop,+ Retighten the bolts Several More Times.........<br /><br />Finally Figured Out What Happened.............<br /><br />I Didn't remove the Fresh Paint from the Bevels the Shoulder of the bolt rides in,...........<br />They were TIGHT,........ Then the Paint would break down,.. And they were Loose Again..............<br /><br />Luckily,.... That Nightmare ended after 20 miles or so......... <br /><br />"Torque 'em and retorque 'em. and then torque them again."<br />Ayuh,................... ;)

Re: lug nuts torque

My Rougue trailer has 5 lug hubs and has galvanized steel wheels. The manual for my trailer specs 90lb-ft of torque for the lug nuts.

Re: lug nuts torque

Torque and "clamp load" are two entirely different properties.<br /><br />You can get a good torque reading and your clamp load (important) can be quite low.<br /><br />To help with clamp load, apply lubricant to the threads. Do not use grease, us e a dry lubricant.<br /><br />Torque the studs to the specified torque (I'm guessing 90#). Do NOT overtorque, with lube, you'll snap them off. :eek:

Re: lug nuts torque

Standard torque rating for most trailer axles is 85 to 90 ft lbs.

Re: lug nuts torque

Thanks Craze That,s the kind of answer I was looking for. Short and straight to the point. Yea I checked on a few trailer sites and the range was from 85 to 110. I figure I'll go with 90. Is using a little locktite medium out of the question? The blue?

Re: lug nuts torque

I wouldn't use loc-tite. Before it dries it acts as a lubricant and alters your torque reading. All torque specs on ANY wheel on any vehicle are based on clean dry threads. Lubing with anything makes them too easy to turn and causes you to over-torque. I wouldn't recommend lubricant of any kind on any lug nuts. Do a quick search on "lubricate lug nuts" on any search engine for all kinds of reasons behind the "no lube" theory. I doubt you'll find many mechanics or manufacturers that will recommend doing anything to a lug nut besides cleaning the threads (wire brush) and setting to proper torque while dry. Then recheck every so often to make sure they're not coming loose.

Re: lug nuts torque

I am a mechanics instructor, certified in heavy equipment, heavy & med truck, auto, and RV (trailer). 90 ft lb is probably safe. I lube ALL lugs with anti-seize compound (eg Permatex 133K) and use mfg recommended torque. If you anti-seize, your life will be better, I promise.

Ayuh,........<br /><br />I'm in the Exact same boat,......Except,.. I'm the Mechanic with over 30 years experince,.... And Agree Completely.......<br /><br />I Never-sieze Every lug I install..........<br /><br />Lock-Tite is a Crazy Thought...........DON'T Do It............

Re: lug nuts torque

If the wheels are an alloy then you need to re-torque at about 75-100 miles. Alloy wheels tend to loosen. If they are steel you will be okay.<br /><br />I say install the lugs clean and dry.

Re: lug nuts torque

OK, OK. I forget how many other fellow mechanics there are out here. At the risk of being called a waffler here, I'll come out of the closet now and admit to being part of the Permatex anti-sieze crowd...it's also something I've done to all my lugs over the past 20 years or so of wrenching, but didn't really want to say it out loud as it's not often written as a recommended procedure for liability reasons.<br /><br />People need to be aware though...as helpful as that silver magic it is in keeping them from siezing due to galvanic corrosion, especially on aluminum wheeled setups, it can be just as helpful in causing unmaintained lugnuts to work loose. So anti-sieze is fine, but makes it all the more critical to torque them properly (if undertorqued they'll come loose, and overtorque will snap studs real easy with antisieze), and then follow up by re-checking torque frequently. Not a lot of recreational trailer owners do this maintenance very well, so many mechanics and service manuals prefer to risk a siezed nut by recommending dry assembly, since a siezed nut is always safer than a loose lugnut. <br /><br />Just remember you have less margin for error when you use anti-sieze.

I agree. Salt water & heat can make unprotected lugnuts very difficult to remove. You likely won't have you're best tools available when you need to remove them. ;)

Re: lug nuts torque

My fellow mechanics make vlauable points. I also recommend that alloy wheels be re-torqued after the first "run" and periodically thereafter. Anti-seize, used sparingly only on the threads, actually has little affect on "working loose". The problem comes in when overused and when it is used on the tapered contact surface of the lug. it is also helpful on the hub contact surfaces of an alloy wheel, but again: use spareingly. A thin coat is all that is needed.

Re: lug nuts torque

As a fleet tech and master heavy truck and automotive ASE tech for over 25 years I read with interest the ideas of proper torquing of lug nuts. "All lug nuts should be installed dry" is not what Ford recommends on their "F" series trucks. Just a point of interest as most boat trailers do not use this type of fastener. A small amount of lube on the lug nut 'washer' is required. As far as anti-seize, use the proper type of anti-seize (there are several different types for different metals). Apply the anti-seize only on the threads to prevent galling during removal. You must reduce the applied torque by about 40% or risk overtorquing. I use stainless lug nuts and must use anti-seize formulated for stainless. The 45 degree cone is what prevents the lug from backing off, however as the metals seat in, the nut should be retorqued to maintain clamping force. Loctite is great for protection of the threads during installation and removal. The proper loctite will seal the threads and prevent water intrusion. It will not adversly change the torque spec.

Re: lug nuts torque

Torque specs are for DRY threads unless otherwise specified. I would advise against using anit-seize products. Just clean the threads with wire brush and torque. If you are afraid of them corroding on, back them out and retorque once or twice a season. Anything you put on the threads acts as a lube and causes the lug to stretch and snap at a much lower torque reading. Even if it doesn't break on you, it is much closer to its failure point than if it was torqued dry.

Hey Boatz...how do you like the internet? Ask a simple question and only get about 8 conflicting answers...<br /><br />Now you get to sort through the mess....<br /><br />That's why I like this place, its fun!

Re: lug nuts torque

You are not supposed to put anything on stud threads. That being said I have no experience with running trailer studs on boats. So I need to find a method that works.
