Got my new Ivo light 68" ground adjustable prop in. Sure is smooth on runup and love that easy ground adjusting method. Weather won't allow inflight test yet though.

The supplied 8mm mounting bolts work but are a little long for my taste. Once properly torqued, the threaded end comes within a few mm of touching the 'C' gearbox housing. Also, I'd feel better if they were drilled and I could safety wire them too.

So the question is, can one get shorter 8mm AN quality bolts with the heads drilled? Should I just use drilled AN5 bolts instead? Or, should I just add some washers on the face of the prop hub and not worry about safety wiring?
