Driving lights, mounting bolt thread type?

[pugfrank 14 1 Cars]

Hi,

 

I had to cut off one of the nuts securing my driving lights the other day,  want to order some new stainless steel nuts for the pair of lights, am I correct in thinking they are metric fine thread? 

 

Could someone tell me the diameter and pitch of thread please? 

 

Thanks

It’s worth learning to identify threads yourself. Male threads eg studs or bolts are easy.

An open end spanner is a very easy way to get the diameter.
For the pitch count 10 threads and measure the length. Then divide by 10. It’s easier to be accurate as say 10mm to 12.5mm to 15mm is much easier to read off a rule than 1.0/1.25/1.5mm.

Alternatively a set of pitch gauges is not expensive.

Top tip Tom, thanks.
