What size bolt holds the bed on?

Just realized mine has only one in it. Bought took the one up to Lowe's, but they didn't have anything to match.

Thanks for the info.

go to tractor supply thay have lots of nuts and bolts and there cheaper.

Are bed bolts available through a dealership? I can't find a damn bolt that fits. Ever drive a truck across town to storage w/o the bed bolted down?

I think i have a couple in the shop.If u will give me some idea of how long ur bed bolts are,I will send u these two if they are comparable.they are round head square shoulder I know--how long?BJ

I'll measure them in the morning. Thanks. Any number helps.
