Which joist hanger to use for outside porch

2x8 2x10 is the better option

Gizmo is absolutely correct: use the bigger hanger. Then fill all holes with exterior quality nails.

Re: Which joist hanger to use for outside porch

Hangers say 10d and 16d HDG.

It seems like it's either swinging a hammer, buying a mechanical fastener gun (maybe.. if they drive 16d), or a palm nailer.

Should I consider the palm nailer?

a hammer is fine, if you want to spend the money a palm nailer is alot cheaper than a "bosch sure shot" joist hanger nailer.

if i was only doing one deck i would do it with a hammer and joist hanger nails. they sell the nails at the big box stores.

Re: Which joist hanger to use for outside porch

The hardware (hanger) says to user 10d or 16d common -- those joist hanger nails are much shorter is what I understand. The angled (toenailed) 16ds will pass through the hanger, the joist, and into the ledger. The ones going only into the ledger, will pass through ledger, and into the house rim.

I've always used nails as follows:
- The nails into the header: 1-1/2" long.
- The nails into the joist: 2-1/2" long, so they go into the header as well.

Simpsons says to use 10d (single 2x hangers) and 16d (doubles, etc) - even for the ledger side if I read their info correctly. I guess it's not going to matter much to me -- I may as well go with the larger nail. Thinking seriously about a palm nailer though.

Re: Which joist hanger to use for outside porch

Did a little experimenting with a palm nailer.

Are screws an option?

Unless the manufacture says you can use screws, and most likely they dont, then you cant. The difference between shear forces of screws and nails are drastically different.

Also, remember ear protection when using a hammer so long :)

Best to follow the hanger manufacturer's directions. Most I've used require 16d galvanized nails in diagonally-driven locations and 9d 1 1/2" joist hanger nails where driven across the width of the joist. I have used exterior grade screws for these and I believe they will hold better, but you must be sure they are not brittle like sheet-rock screws as those will snap under a load as they are too hard. Also be sure the ledger band is attached to the house with lags or carriage bolts every 24" or less as many decks and porches have fallen when nails pulled out.

A palm nailer can make working in the tight spots a lot easier. For one or two jobs a cheap one will do fine. Once you do these with a palm nailer, you'll never go back to the smashed fingers of nailing hangers in with a hammer!
