HW 80 trigger guard screw.

[p.j.]

Does anyone know the pitch of the front trigger guard screw in an HW80?
Thread size as far as I am aware is M7, but need the pitch as I need to clean out the female threaded section on the cylinder.
The pitch will be important if I buy a suitable tap, other wise will try a bolt with a shallow cut at 90 degrees to the threads.

M7 X 1mm

Thanks thats exactly what I needed.

Now you've got to try and get them in that size, near on impossible!

I don't know where you got that idea from BM, M7 X 1 is common in automotive use and readily available in this Draper set :-
