Just got car back from the garage, only to find the wheelbolts overtightened. Manage to get the bolts slackened and took one bolt out. when i rubbed the bolt threads on my finger There were tiny metal flakes. So, is that something to worry about?

I think you might have a problem, sounds like the threads are damaged and the flakes of metal sounds like its off the threads themselves, happens if there are slightly corroded sometimes

Advice given seems sound.

But, how did you know they were overtightened?

Should be OK, ghe flakes could be off thread being over tightened, it's because a lot of garages put them in with windy guns when they should be put in normally and torqued up.. if it's tightened alright you should be OK to go, just drive a few miles and check them.

There should be no metal flakes on the bolts/nuts

I am a mechanic

You need to take it to the garage to have it checked, don't take a chance that they will be fine and have the risk of your wheel coming off.

had to use a lot of force to get them off. Also compared bolt to one off another wheel which came odd easier and also no fine metal flakes.

Hang on before you start saving he'll be fine,, if there are flakes of metal on the thread they could have been cross threaded being refitted, and the garage air gun won't care if they are, it'll just batter away until its jammed in

Seriously mate, get them checked soon as you can

I'd be more worried about the one that came off easier! Have to say, I've been driving for over 35yrs and never felt the need to check how tight the wheel nuts were when it came back from the garage! Only problem I've had with tightness of wheel nuts was when I under tightened mine once many moons ago.

The metal flakes may or may not be an issue so do as the others suggest and get them checked though.

Hang on, how do you put them back on?

You meant to use a torque wrench. I doubt many do but presumably you have a decent wheel brace at least?

But your kit is not likely to be better than the garage's.

I don't get it?

How on earth did know that your wheel bolts have been overtightened?

Road cars tend to have wheel bolts tightened from anything between 110Nm-150Nm depending on make model and type of wheel construction.

What did you do? Re torque your bolts when you or the car home?

Lots of confusion about this. Not a proper mechanic but i do a lot of tinkering, currently wearing the wounds to prove it (Sliced half my right ring fingernail off changing the brakes on a Fiat Bravo last week).

In any event, not entirely sure why you would "find" a bolt overtightened, but i'll say this, if you "didnt have to stand on the wheel brace" then they werent overtightened to any major extent unless you happen to be a worlds strongest man contestant. If you can rotate the bolt by hand, with a wheel brace only, they arent overtightened. Ive taken off wheels ive had to use a 3ft power bar to crack, never been a problem.

That being said, if you have flakes, its possible they have been cross threaded, which could indeed be a problem and is worth getting checked out with a mechanic just to be sure.

What a funny topic, veiwed it earlier then with my engineer head on went wtf and left alone.

Why are you checking the torque- they have air guns that are preset and do dozens of cars every day I bet.

Are the threads OK?

If Yes, then do back up to the correct torque.

Metals shards could be present due to simple corrosion between the wheel and bolt if adequate grease wasn't applied.

Especially prominent due to alloy wheels being common on most cars now.

You should ignore all the rubbish replies on here so far.

I am a professional mechanical engineer....listen up!

There is an enormous factor of safety built in to the strength of a wheel nut/bolt.

The rare failure is either the nut/bolt coming slack, due to being incorrectly tightened or the stud snapping off due to excessive shock loading or fatigue due to age and `work hardening`.

The chance of a thread stripping is virtually nil and the `overtightening` that you think you had, is more likely to be corrosion....especially if you have alloy wheels.

Be assured...and forget any relationship with the `flakes`which can be from a number of cause.

Lengthy....but correct!!! lol

Enjoy your car.

I was taught tighten completely then loosen 1/4 turn?

And if it was cross threaded you should be able to see that by actually looking at the bolt.

Ultimately, this is not really the place for the answer anyway - ask the garage. Or another garage if you don't trust this one?

Either way- you will have to wait until Monday now!

I still don't see how you can tell if a nut/bolt was over tightened.

It's not like you can just reverse a torque wrench and see the force needed to slacken. It doesn't work like that.

Surely the torque required to loosen isn't the same as the torque it took to tighten? The conditions are different.

"I still don't see how you can tell if a nut/bolt was over tightened.

It's not like you can just reverse a torque wrench and see the force needed to slacken. It doesn't work like that.

My torque wrench does, it holds the highest torque applied on the display.

set torque wrench to colorectal setting for the wheel nuts apply to tighten nuts when it reaches correct tourque it should click to release if it doesent and goes beyond nuts are over tightened simple

But the breaking point force to get a tightened nut moving is considerably higher than the torque used to tighten it.

this is why I ALWAYS slacken wheel nuts and re tighten myself after a tyre change at a garage slack off then re tighten till the car rolls NEVER tighten against the hand break

So much for the amateur know it alls who told you,, yeah mate if there tight you be ok

Never seek advice on here on something so important, you wouldn't ask an estate agent about your health issues, remember the only point of contact between your car on the motorway is a couple of inches of tyre, if the wheelbolts are not completely safe you risk not only your life but a lot of others too

"What a funny topic, veiwed it earlier then with my engineer head on went wtf and left alone.

Why are you checking the torque- they have air guns that are preset and do dozens of cars every day I bet.

Are the threads OK?

If Yes, then do back up to the correct torque.

Metals shards could be present due to simple corrosion between the wheel and bolt if adequate grease wasn't applied.

Especially prominent due to alloy wheels being common on most cars now.

Steel wheels.. Was checking if view damaged anything.. As one garage fucked the threads once and was driving around till a puncture revealed the knackered thread. Also, bolts on other wheels had no metal flakes.. Only the one wheel they took off putting grease on threads would affect torque wouldn't it? "

Not if the correct grease is used....... And as mentioned before this is not an exact science- torque required on wheel nuts for a car is a wide range.......

"Just got car back from the garage, only to find the wheelbolts overtightened. Manage to get the bolts slackened and took one bolt out. when i rubbed the bolt threads on my finger There were tiny metal flakes. So, is that something to worry about?

You should ignore all the rubbish replies on here so far.

I am a professional mechanical engineer....listen up!

There is an enormous factor of safety built in to the strength of a wheel nut/bolt.

The rare failure is either the nut/bolt coming slack, due to being incorrectly tightened or the stud snapping off due to excessive shock loading or fatigue due to age and `work hardening`.

The chance of a thread stripping is virtually nil and the `overtightening` that you think you had, is more likely to be corrosion....especially if you have alloy wheels.

Be assured...and forget any relationship with the `flakes`which can be from a number of cause.

Lengthy....but correct!!! lol

Enjoy your car.

I'm not being funny but what's the point of taking your car to the garage for repair if your going to interfere and tamper with the work they've done? Next thing you'll be taking it back because you've cocked something up and trying to blame the garage for your fuck up!

There are good garages and bad garages and the same same applies technicians. There are also good customers and bad customers and I have met both, the good ones on many occasions, bad ones usually just the once....

Tell me, do you drop your pants in Tesco to check the toilet tissue... maybe get your cock out to make sure condoms fit correctly?

The garage in question would be well within their right to turn you away and void any work they have carried out on your vehicle because you have tampered with it. I personally leave a tiny paint dot on every nut & bolt I've moved and if the dot is broken, any warranty and or goodwill is gone... along with yourself with your tail between your legs.

Vehicle maintenance is a tough, dirty, underpaid job and hard enough without interfering customers with busy fingers!

P.S. If your wheel falls off, YOU are now liable because YOU were the last person to touch it!

Once you've tightened them go to a garage and get them torqued , job done , I would not worry about the metal flakes

It's a pet hate of mine, I detest garages that power on the nuts with a hammer gun without setting the torque..... Makes it nigh on impossible to get them off at the roadside with your normal brace when you do have an emergency... The flakes of "metal" will more than likely be copper grease which you should use on wheel nuts to stop then seizing

I have a big bar which will slacken your nuts for you.

I have another bar you could use to slacken my nuts.

Just to add

Air guns don't have torque settings, well except ones used in motorsport, your average mechanics air gun just has power settings.

Reading some of the posts, glad to know mechanics will still have a job with all the ones saying it will be fine.

Much like the shuttle o rings,chances are you might get away with damaged wheel bolts, but if it goes wrong, its disastrously wrong
