Outdrive Prop Cone Bolt

[keelhauled]

Anyone know the Diameter/Length/Thread Pitch for the Volvo Penta prop cone retainer bolt on a 280/290 lower unit? Mine disappeared! I figured I'd get the size before going to the stainless steel bolt shop.

Thanks in advance!

Anyone know this? I need to know before going to the hardware store. Mine has gone missing.

The prop cone center screw / bolt is a 5/16-18 x 2" long stainless allen head screw.

I am very surprised this isn't a metric screw.
