how much thread is needed in wheel spacers?

[def90]

ok so i bought some whel spacers cheap from the states of fleabay, and on a mock fitup i noticed that they only get about 5 turns on the wheel nut (rovers have short studs and bid nuts and thread). i spoke to a wheel fella who is doing some work on my beadlocks and he says that you need at least 7 turns on a stud for strength. now these will be used for 'offroad road use only' and i thought 5 turns wasn't a tad ordinary as well?

i can get them machined out for $30/spacer, but is it worth the coin? i'm leaning toward a yes.

i've never had wheel spacers before.

For normal industrial bolting applications you should have engagement of at least 1.2 times the diameter of the bolt, so if the thread was 10mm dia, the engagment length is a minimum of 12mm. You should have more for higher load situations. I am sure if you can put your hands on a copy of 'machinery handbook', you will get a good guide.

shot in the dark, but what about using longer studs on the wheel. itll be better than machining down the spacer. but as PBBIZ2 said, industry standards say at least 1.2 times the bolt dia.

another rule of thumb is that you should have the nut fully threaded onto the bolt or stud and have 2 full threads protruding.
this is because rolled threads taper of at the ends so the end couple of threads on a bolt wont be the full diameter of the rest of the bolt

x2 on longer wheel studs

Agreed
And they only cost a few $

I'm having the same problem the moment also with my wheel spacers.I priced new studs at $8 to $10 each.

snake racing are $10 and autobarn are $8 each.I need them for a hilux.if you know of anywhere cheaper let me know.

thanks for the replys. i don't understand how longer nuts on the wheel helps the small bite on the wheel spacer? (excuse my ignorance). the wheel spacer nut, which is obvioulsy enclosed within the wheel spacer has not much bite on the original wheel stud. longer nuts won't help this as the surface in between the wheel spacer wheel nut and wheel stud is to great to get the nut in any further, thus needing to machine that surface down to get more bite and stay enclosed within the wheel spacer so the wheel/rim doesn't fowl on the spacer - if that makes sense?

from the given posts i think i have to machine down the spacer (where the wheel nut joins the original thread) so that it bites to the extent of at least using the full nut on the stud, or even further using the 1.2 times the diameter - which is approx 16mm x 1.2. after measuring the nut that came with the spacers they are 16mm (the dia. of the wheel stud), so i'll at least go for that or roughly 2 turns or 19mm on the original thread.

have i spoken turkish or does this make sense?

[80's_delirious]

have i spoken turkish or does this make sense?

a picture tells a thousand words (in any language)

the suggestion was for longer replacement wheel studs to be fitted to the hub so that the stud sticks through the wheel spacer far enough to get the nut fully threaded on while still being enclosed within the wheel spacer.

make sense?


and no, I dont speak Turkish

I didnt understand Untill 80's_del spoke Turkish
Now thats how I read it

studs, not nuts. nuts wont do shit if there isnt a stud to put it on.

Thats what hes trying to achieve I think
Getting more of the nut on the Stud

[hiluxmad]

leave autobarn and snake alone for this type of stuff go to repco or similar and ask for trade price.
the mark up is

yep sorry read the post wrong, thats why i was confused when i thought it was said to get longer nuts, of course that will sweet freddy all.

i think i'll wing it for now, wheel studs are 25mm long, there is about 10mm of meat on the spacer (measured from the bottom of the little bevel), that gives me roughly 15mm on the thread, actually near 7 turns of the nut.

so in other words they will never get used
