Thread size

[shagster]

i am looking for some help.
We have been playing with some titleist 910 and 913 head and shaft combinations, and one of the threads has picked up, and not sure what thread size is, as I need to run a tap down the thread to clean it up.
Many thanks

Are we talking driver or fairway shafts.

You're aware that the driver shafts are interchangabe between 910 and 913 but not the fairway woods as the surefit adapter is different?

As for thread size, I can get a gauge from work tomorrow to measure.

Thanks Gareth. Yes they are both drivers.
It looks about 4 mm but not sure.
Thanks

Go careful until gauged though could be m4 fine or even unified!

And several others ha ha
I have measured the screw and it comes in at 3/16, and I believe titleist is american, so I suspect it would be unf, but any other info, much appreciated

Thread turned out to be 3/16 unf or 10 / 32 tpi.
Very hard to find a tap though, luck with a small back street garage

3/16" UNF and 2BA are the same. (Or close enough to pass)

Thanks Clive , but the thread angle is quite a bit different.
I was lucky and found a tap so have sorted out minor problem
