correct prop bolt size BME115
 

what is the correct size of the prop bolts on a BME 115 10/32 or M-5 I'm switching to a Vess an need to increase the length

How old is it? The new BME's use 10/32 . If its more than 1 1/2 years old is probably a 5mm

They are all 10-32.

Bear in mind that the 10-32 screws are not the primary clamp fasteners for the propeller. The center nut is what is used to provide the propeller clamping force. The outer 10-32 screws are more for indexing and anti rotation pins. You only need to use two of them. Using only the outer screws to retain the prop on a 115/116 will cause propeller and/or hub failure.
