Prop bolts?

[fiveoboy01]

What's the thread size/pitch for the prop bolts on an 0360-A4M?

I have been loaned a nice bracket which will enable me to bolt the engine to a pallet but I need to grab some short bolts to attach it to the crank flange. And I don't want to run to the hangar and then backtrack to the hardware store in the morning

Thanks.

Just a WAG here, 3/8-24? Course being an airplane part they're probably a -28, just so you can't do what you plan.

This guy is correct. I took a prop bolt to Menards this morning
