I was going to replace the screw that holds the nozzle shut-off pin to the handle
RCBS' directions say this is: #81115 Round head screw 5/40 x 3/8
Now I'm guessing the 3/8 is 'of an inch'
But what in the world is 5/40 ????
I took the shut off pin to the hardware store and the threaded hole is somewhere between 4-40 and 6-32 as well as also not being a metric thread either.
thanks in advance
