I feel some context is required
My nuts are just dandy, thanks. Done up to at least 4BN Nms by my local tyre place (Motto: "If the car's not rotating, they aren't tight enough!")
Some may remember I'm running Cross-sized tyres (185/65 R15s) on my 4x4. Reports were that some people fitted them nae problem, whereas others reported some rubbing on lock. And so it proved, with rubbing when I next swung around in the school entrance. Not a problem, 5mm spacers sort it, and so I fitted them. All well, no rubbing, happy days for the next 2+ years.
Well, happy days until we came to a test drive with a prospective new purchaser on Friday, when we discovered, much to my embarrassment

that on
absolute full lock in reverse it was possible to get rubbing (on the subframe I assume which already has a cutout, I recall) Obviously I'd not done a
full lock reverse in 2 years, but there you go! It may also be connected to the Vred All Seasons I'm running at the front, which have a noticeably broader profile than the Kumhos out back - a different tyre might have enough clearance.
Anyhow, easy enough to order up some 10mm spacers, and that will make absolutely sure that the 185s won't rub - but I need to order some new bolts as the current ones will be too short for safety. So that, in a much bigger nutshell, is why I need to be sure of the OE thread length & pitch so I can add that 10mm. I may have kept the old ones, or the garage may have retained them, can't remember. I can always go and wrangle a bolt off in the rain and measure it, but I confess to some laziness on a Sunday morning (I assume that we have 48.5 as the standard thread length from the Febi bolt you linked
@Herts Hillhopper )
So there you go, there's always a backstory to even the simplest query!
BTW, the car sold
