Bolts for F9000 Sleeve Bags

Does anyone know what size bolts to use with the F9000 Sleeves?

i dont know the size but if you got the bag then just take it with you into home depo or lowes and find the size u need. sure they will be some confused people there but it works lol.

I didn't write the measurement down,but just stick something small into the hole & mark than measure it.Use a bolt a little shorter or a flat & lock washer so the bolt can not bottom out!

They are 3/8 by 16. Check out the link I posted, the page has all the specs on the F9000.
