Take the point entirely and that's my job exactly as you say, for tomorrow morning Beattie. Can't believe that I'd missed that it was 1/4UNC thread. Staring me in the face.

Peter, yes, It was only 1/4 UNC.

My car only had 1 of 2 wingnuts when I bought it so I had to do something. I made 2 so they would look alike in the engine bay.

If I had original parts needing saving I would use a HeliCoil (ReCoil... whatever brand you like) for the thread repair. Though HeliCoils are not the best in all situations this is a place they would be ideal. The pilot drill is 6.7mm (17/64") and the OD of the installed insert will be close to 5/16". That leaves the original wingnut a reasonable wall thickness compared to a lot of other thread insert types.

DOWNTON Mini is what I like a lot.

For a non-original but perhaps more stylish solution what about these? ... etrosport/

Available in long or short versions and a selection of colours and finishes.

I found these perfectly acceptable, albeit not cheap, and they're made in England!

(Rich/MiniSpares, is there a particular reason for this? I'd imagine you would sell quite a lot of these.)
Actually, these are being reproduced...on E Bay....30 pounds a set. ... SwEeFU9dst

The reproduction ones aren't the right shape.

Nick has them listed. I bought a pair a few years ago ... cts_id=632

The one on the left is the right type for early cars
