How to find a replacement engine bolt without measuring another one

Does anyone have any godly idea as to where I can buy a singular engine valve cover bolt for the rear engine? I can't even find them on official Ford parts sites.source ↗

I just replaced the water pump on my 2007 Honda CRV and as I was (blindly) putting the last bolt in it slipped off the wrench and for the life of me I cannot find it.source ↗
