Louvre Window Knob Screw

Anyone know what the size and length of screw needed to fix the Louvre window knob to the winding mechanism? The is a westy window rather than Devon

Thanks

 

I think they're the same size as the screws for the window winder handles.

 

You said knob screw hehe

 

I can tell you Monday as I have two new mechanisms at work

 

It's smaller than the window winder. I bought a lovely new ali knob to reward myself for the 3 months of polishing the window and promptly lost the screw :-(

 

I'd guess metric M4 or M5
