I've been surfing the web for a prop nut for my OS 30 4 stroke. Been looking at the tru-turn ones and just can't seem to find the right one to use. I've emailed them but alas no response.

Would this be the one to use - TTN-0625-A-140 to use for my engine as I'm looking at using it on my Great Planes 20 Sized Cub.





Appreciate the help, - Hansen

Here is the manual for your engine.

They have a breakout view of the engine in the manual. It lists the OS part number as 45810100

The nut you are looking for is a standard thread of 1/4-28
