Help. Has anyone got a M11 x 2.0 tap for seatbelt bolt threads?

About a 17 years ago I had anchor points welded into the C pillars of the oval. Now I've finally removed the roll bar and I'm putting seatbelt a in the back.

It was really tricky to get the bolt to find its threads in the drivers side bolt. It took about half an hour. The passenger side has been even more tricky. All I need is a tap to clean up the thread.

But despite the millions of cars driving around Aus wth these bolts nobody seems to have a tap for this unusual thread.

I can get one custom-made by Suttons tools in England which will take 9 weeks and cost $200. So I can use it once!

So does anyone have one I can borrow or rent and return?

I don't want to drill the bolt out to an M12 as it may cause safety issues for the cars future custodians.

Thanks

Standard seatbelt anchors in Australia are 7/16" UNF 20 T.P.I (11.11 mm x 1.27 pitch). Are you sure that you haven't got that size. If you had it done around 2000 then it would have been done to the Australia Standard (ADR) of 7/16 UNF.

I think that I would prefer to use the correct tap.
I read it on samba, so it must be correct.

Sometimes Volkswagen dealers sell spare parts. Amazing isn't it!😂

You should use 7/16 UNF high tensile bolts, or else increase your public liability insurance, CT.
I'd rather wear a Beetle out by racing it than by polishing it!

Thanks for your help everyone.

I think Mackaymax is right. Thanks 🙂.

The tool shop I took the bolt to sent me down the wrong path by accident. It seems so much more logical that it's a common 7/16 UNF thread when you consider how common seatbelt bolts are. I bought a 7/16 tap yesterday and I'll try it in the harness plates first.

If you did get a M11x2 tap, where would you get the bolts from anyway?🙂

7/16 is almost exactly 11mm and as far as I know the 7/16 seat belt bolt size has been an worldwide standard since the 70's.
madness is in the eye of the beholder 👍

Yup 7/16 UNF. It was a bugger of a thread to fix. In fact it felt like I was taping an entirely new one. But it's good now.

Thanks everyone.
