Hi,
Can someone tell me what size and thread are the wing nuts on the gauge panel of the TR 3? I lost mine and need to buy four new ones!
thanks,
Dennis

The brass whitworth wing nuts are difficult to find. Not off the shelf items unless one of the big 3 contracted some out. Marv may have some used ones, though?!?
 
I thought Triumph used US sizes wherever possible. I chased the threads with a 10-32 die
and felt no resistance at all ( & no metal shavings) so I bought 10-32 brass wing nuts at
the hardware store.
 
Funny, I always thought they used Whitworth as much as possible just to mess with us after that "revolution" thing, LOL. A few of the whitworths are close enough to retap to more standard threads. Others are not.
 
10-32 is 32 TPI 0.190 dia and 2BA is 31.36 TPI 0.185 dia so there is almost no difference between them. It may be harder to get a 2BA to nut to go on a 10-32 bolt than a 10-32 nut on a 2 BA bolt.

Will save the British nut joke for later.
