[TR] TR] Rocker Shaft locating screw

[Roger Elliott]

The locating screw is smaller than 1/4 inch.  Hard to tell that in the 
picture below.  More like a #12 screw.

The locating screw seems to screw into a M6x1 sizer at the hardware 
store.  But strangely a M6x1 bolt won's screw into the hole.

It appears to be 27tpi according to my gauge.

Looks very close to m5x.8

Thanks,
Roger
