Wanted Battery hold down bolt

[trukman1]

I bought a wedge type battery hold down from NAPA and from online search thought I needed a 8mm x 1.25 bolt but that is too big, 1/4" is too small and 5/16" is too big also. Anybody have one or know what the correct size is? All the parts stores tell me its 8mm x 1.25 but the one I bought won't begin to go into the hole.Afraid to drive without it. Thanks! Gary

ETA: I know this seems trivial but I'm just trying to get my vehicle safe to, finally, get to drive. Thanks again!

Have a 5/16” tap?

Yes I do. I will try that. I tried a 5/16" bolt but it wouldn't start so I thought I needed something else.Thank you.

Run a 1/4” drill through there and go slow when you run the tap

Well, 1/4" tap was too small but the 5/16" tap did the trick! Battery is now locked in place! Thanks fellas!
