What threads are the maxi balljoints?
I bought my maxi balljoints as part of a package from somebody on the anti Chris Gibbs forum and unfortunately I only received 1 nut. Now I have the car as a rolling chassis the bottom wishbone just falls out with no nut to hold it on.
So what is the thread, and does anyone possibly have a spare nut? Thanks! Sam |
surely somebody must know?

I got mine from ebay, and they came with nuts. I'll measure them up tonight, unless someone beats me to it :)

Or just very gently try a few nuts on it to see if one fits. I have a sneaky suspicion it might be imperial Sean |
I believe they are 7/16" UNF
Had a quick look but have every possible Nyloc nut other than that one :confused: :confused: |
from memory i think they are to corse to be 7/16 but i could be wrong.

Maxi ball joint thread
Right this is the best I can do
I have two different brands of ball joint, One is made by Veco & the other is made by QH. Both have the same thread. I have just put my digital caliper on them. In metric the diameter of the treaded part is 11.9mm Now here is the problem :confused: :confused: Both the 20 TPI & 1.25 thread gauges fit the thread. My Osborne cutting tool guide lists the following Two possible sizes. M12 X 1.25 is a standard metric fine thread 7/16" X 20 TPI this is listed as a UNF thread size Looking at my metric conversion chart, it is noted that the mertic range for 7/16" is 11.112 - 11.5mm So given the outside diameter of the thread, it is probable that the thread is M12 X 1.25 ( Metric fine ) But I would not still rule out the 7/16" UNF in view of the possibility that this component could pre-date the metric era. Please remember, This information taken from my tool guide & intended as a guide only :) With a little luck, some of the more able engineers on the forum will have an exact answer. ;) |
thanks guys.
An M12 nut will grip the first thread only then not screw down any further. I can see me having to go and buy another balljoint just for the nut :( |
A standard M12 metric nut will not fit
If it is a 12mm thread it will be a M12 X 1.25 thread pitch. Probably your best option would be to vist your local steel stockist or engineering fixing stockist ( Take the joint with you ). Either should be able to give you an exact answer. Both 7/16" UNF & M12 X 1.25 are available on ebay ;) |
just take it down the local fixings shop and get them to find a nut that fits it.
my local chap managed to get me m18 1.5 fine nyloc nuts. took him 2days to find them but those babys are like hens teeth |
