What is the thread size of hex Bolt BS691147?

[AD56]

Lost this bolt off my 4.75 HP B&S mower and am trying to find another one today at Ace Hardware....
It fits the gasket over the oil pump cover for my B&S model 12H802-2672-E1 engine.
Any help is appreciated.
I’ve been searching for a couple of hours but can’t get the thread size/length etc...
I really need to get mowing TODAY.

The motor is probably full of the same bolts, take one that is not so important from somewhere else until you find a bolt.

Thanks.
I had thought of that after I posted.
We went through about every similar bolt we could find at Ace.
No go.

I did speak to a very helpful and nice young lady at Briggs & Stratton Support after a long wait.
Turns out the part I need is MTD BS-691092.
She didn’t have the specs on that bolt available to her via her database.

Going to order online and wait a few days for the Pony Express to show up...
Thanks for the response.

PS- I’ll set the wheels higher and mow twice.......
