Checked tractor supply and a local hardware store. Can't find 7/16x5 course tread grade 5 or 8 bold and nut anywhere. Google didn't turn anything up either. Where can I find these?? Running a TH marine jack plate and a TH marine transom support plate and the 4" bolt is way to small. Thanks guys!

I'd suggest 1/2-20 fine thread for motor mount bolts...

If you dont want to wait on the mail or ups u can also get said bolts at a Fastenal store. Thats where I get my stuff when needed.

I have 5.5 Merc kits in stock. 4 1/2 fine bolts, 4 1/2 fine brass nylocks, 2 large SS washers and 2 small SS washers.

Mcmaster has a New Jersey warehouse, you'll get them in New York next day if ordered by 4 PM. They seem to have some kind of "preferred" UPS account because shipping seems well below normal UPS rates, I usually pay about 4 bucks for small items like a bag of bolts.

Switch over to 17-4 ph McMaster has some if not might be able to get them
17-4 is more than 3 times stronger then 300 series
