Now sorted thanks :) - Help with metric thread types please.

[DJ.]

I'm looking to buy nyloc nuts ready to use when I replace my differential, and I've just found from the Namric site that there are alternative thread pitches for each diameter.

 

I need to buy M10 nuts for the hub carriers and M12 for the A frame.

 

Namric say standard metric threads are too coarse for automotive use, so I assume the nuts are:

 

Either metric fine M10 1.0mm pitch or

M10 1.25mm pitch

and either M12 1.25mm pitch or

M12 1.5mm pitch

 

If anyone knows which ones I should order, I would be grateful

If you have the paper lists from your fastner packs you'll be able to find it by comparing with the build manual. In the text there's a reference.

 

Unfortunately I don't have these for a metric car.

Thanks for that, unfortunately it just says the bolt diameter, length in mm and grade on those sheets.

 

It is more helpful for the imperial bolts eg 1/2 UNF

Generally with metric, if no pitch is quoted it can be assumed that they are standard pitch.

 

But there's always going to be an exception to this.

Second this

Thanks very much for your help

Std metric thread is 1.5mm. Metric fine is normally either 1.25mm or 1.0mm.

 

M10 x 1.5 is what is used on the hub carriers and DD ears. The grade used is 10.9 but this applies to the bolts only.
