    Extra long Wheel Bolts for 20mm spacers

    Quick one, I've just ordered some 20mm spacers, but need the bolts to go with them.

    I know the bolts are M14, with a 17mm head, but how long should the bolts for a 20mm spacer be?

    And should I be looking for M14x1.5?

    Also any advice on where good places to buy them from would be good, as I have no clue.

    Cheers.

    where did you order them from? They should supply the correct bolt with the spacers...at least DPM did this when I ordered mine...

    They're wolfrace spacers, and didn't come with the bolts. I may drop Damien an email and see if he can supply me with some bolts.

    Any other suggestions on where I can order these bolts from?

    20mm spacer should bolt to the hub then the wheel bolt to the spacer so youd have 10 bolts per hub... where are the spcers coming from or what make???

    Surely you mean adapters? The 20mm spacers I've always had have always bolted via the 5 longer bolts directly via the wheel, with no need to bolt to the hub first.

    Bhav - I'll tell you when i'm home within the next hour. I had to buy extended locking bolts for my 20mm spacers and i bought TPI racing ones off Ebay. I'll post the Ebay link when i get back. The lock bolts i bought are the ones for 20mm spacers so the measurement will be the same as a normal wheel bolt.

    Cheers all, Kev they're hubcentric spacers so will bolt directly to the hub. As long as the spacer and wheel fit snug on the hub the weight will not be taken entirely by the bolts but also by the hub, so they're prefectly safe.

    If they are 'hubcentric spacers', then they will bolt to the hub using new bolts, and then the wheel bolts to the spacer with the original bolts.

    Otherwise, the standard wheel bolts will not be long enough to go through the spacer so you will need bolts that are 20mm longer.

    With 20mm spacers the ttshop gave me 47mm bolts. That was part of a kit. I trust them myself

    My hubcentrics just use longer bolts, if you have a 15mm spacer that bolts to the hub you only have 15mm max thread holding the wheels on ...mmmm.. think about it....

    I've had/got hubcentric spacers (not adapters ) form FK/H&R and Forge and NONE of them ever bolted to the hub first. Whats the point? Thats the whole idea of them (hubcentric) having a lip so they fit the hub perfectly! How could they? They would change the pcd that the alloy was meant for as the original hub threads would be occupied with the bolts used to bolt the spacer to the hub!

    PCD adapters and bolt-on hubcentric spacers have new bolt holes in between the bolts that hold the spacer to the hub. If that makes sense? lol

    I know what you are saying but kev says he has 15mm spacers bolted to the hub ...would you trust 15mm MAX of thread holding the wheel on it would be proberbly be more like 12-13mm then they would hit the hub....

    Im not saying it isnt true but i thought adapters would have to be at least 20mm thick....

    I had 15mm spacers and never had a problem?

    In a real sense though, on a standard car with standard wheels and bolts, how much thread is used on a wheel bolt in the hub?

    When i was checking what size bolts i would need on mine it must have been 25mm+ easy, dont forget you have the thickness of the disc before it hits the threads 3-4mm?

    its 7ish turns of the bolt to hold a wheel on, usually on vag cars. 1.5 thread thats just over 10mm of thread "engaged" if you know what i mean?

    bolt on spacers have 10 holes thru them and come with 5 bolts of there own, to bolt to the hub. the other five holes are threaded, you use the standard wheel bolts to bolt the wheel to the spacer. there not so much simple spacers but "hub extentions".

    i have a pair of 4x100 fk bolt on spacers for my e21 bmw to enable me to fit vw steel wheels on the rear at drifting days.
    e21 bmws use et13/14 wheels as standard. most vw wheels are et40something. so i use the 25mm fk "hub extensions" to correct the offset of the wheels to somewhere near it should be.

    Just a bit strange as to why you would/it would bolt to the hub if it isn't designed to change the PCD (justifying new holes in the spacer/adapter pleate). I've run as much as 25mm spacers out on the rear on my old R33 Liner for 14 months and never had a prob with it. Done the same with 20mm on my B5, an old 21 turbo and a lancia. Never ever heard or seen of spacers bolting to the hub that weren't intended as adapters. But still, bet they exist, so I'm not doubting it, just querying it thats all.

    For 20mm spacers you need 47mm m14x1.50, for 15mm you need 42mm m14x1.50, then radial if you are on standard wheels, tapered on aftermarket jobs. You should get 8 rotations into the hub for safe fitment, that's about 12mm of thread

    I personally think it is safer going through the spacer into the hub, on hubcentrics....
    look how easy it is to strip threads in alloy.....

    the h+r's i had were alloy spacers with steel inserts they were some awsome kit and id rather have that then really long bolts myself, cant see either being less safe theough tbh as they all have to by type aproved at the end of the day. how many cases of failed spacers have we seen? i havent. my 15mm fk's though are just alloy with no insert there a bit more scary lol but only do a few miles a year on them though

    How could this of got so confusing? If the spacer is 20mm thick you will need to have a bolt 20mm longer than a standard oem bolt, Am I missing something here?

    its not complicated but there are 2 styles of wheel spacers, ones like you have where you have extra long wheel bolts and ones like i have had/have got that bolt to the hub then the wheel bolts to the spacer

    here is a pic of my h+r bolted to the hub, 25mm spacer in this case


    then here is my 10mm h+r spacer which is on the hub ready for the wheel to be bolted on with 10mm longer the std wheel bolts


    having thought about this after looking at the pics and from memory id also rather have the bolt on type as its easier for getting wheel on and off

    No I completely understand there are two types of spacers kev, I bought my fk spacers purely because they were half the price of the h+r bolt on ones. What I mean by 'getting complicated' is when people start talking about '7 turns of the bolt' '8 turns' 10mm 12mm ect... All I'm saying is to get the same length of bolt (that audi intended) back in the hub all you have to do is add the thicknes of spacer to STD bolt length

    yea very obvious and simples. But I don't think the poster bothered measuring the standard bolts, if there like me they didn't. Just for ease the size is now posted, and the 8 turns is just for reference really. This thread is far too big for such a simple question though..... Doh I just made it one post bigger
