Is it better to use nails or screws for joist hangers?
The nails penetrate into the wall ledger and therefore offer both better joist load capacity than standard-duty hangers and more protection against uplift forces caused by wind.

A. If the joist hangers your carpenter used are approved for use with the newer ACQ treated lumber, you should have nothing to worry about. These metal framing connectors have been around for years and they are code approved. They don’t have the inherent strength to support the weight of a deck or any framing member.
What can I use instead of joist hangers?
Alternatives to using metal joist hangers are ledger strips, sliding dovetails or mortising and dowels. The methods vary depending on whether it is an exterior deck or an interior platform. When it comes to outdoor decks, the only plausible do-it-yourself technique would be to use a ledger strip to support the joists.
Do you need joist hangers on rim joist?
When a beam supports the joists from below, securing the rim joist to the field joists with through screws will save time over using hangers. Also, in this situation hangers are redundant because the rim joist carries little weight. The main function of the rim joist here is to keep the joists aligned.
Can 2×6 be used for deck joists?
2×6 joists should only be used on ground-level decks that do not require, and will not provide for, any guards. Most decks use 16″ on center spacing for joists. Most decking is not strong enough to support longer spans than 16″.
Can I use 2×6 joist hangers for 2×8?
Usually, the hanger size is the same as the joist size, but you can use a hanger that is one dimensional size less than the joist depth—a 2×6 hanger can be used with a 2×8 joist, for instance. Keep in mind that the load capacity of the smaller hanger needs to be adequate to support the load on the joist.
What size screws joist hangers?
A standard 2×10 hanger requires eight fasteners. Using #9 screws will still support the joist sufficiently with 350 extra lbs to spare. Both screws and nails will support the deck, but #10 nails will do even better.
How do you reinforce deck joists?
Reinforce the Joist Apply a clear sealer and let it dry. Position the reinforcing joist tightly against the damaged joist, and attach it with 16d (3 1/2-inch) galvanized nails driven every 2 feet or fasten it with 3 1/2-inch galvanized deck screws.
Do joists go on top of beams?
You typically need to hang a joist if the top of it needs to be in the same plane as the beam that supports it. There are all sorts of reasons and conditions on jobs where this is necessary.
Which way should deck joists run?
On most decks, the decking boards run parallel to the house and across the joists (either perpendicular or at a 45 degree angle).
How much weight can joist hangers support?
These hangers are bent to 45 degrees and can be installed with joist hanger nails using the same method as straight joist hangers. Angled joist hangers should be available at your local lumberyard for 2×6 and 2×10.Joist Hanger Vertical Capacity. Joist Size Min Capacity lbs 2×6 400 2×8 500 2×10 600 2×12 700.
How much weight can joist hold?
That means the joists can support a minimum of 40 pounds per square foot live load. Though, by consulting the 50 pounds per square foot live load/10 pounds per square foot dead load table, you can see the joists’ span would need to be reduced to 11 feet 11 inches to support heavier weight safely.
Can joist hangers be used for floor joists?
Joist hangers not only simplify the framing process but also strengthen the deck or floor you are building. When hanging floor joists, use joist hangers to make building a floor deck simpler. Place hangers every 16 inches on center. Position each hanger using the tab to hold it in place.
How do joist hangers work?
Joist hangers provide support underneath the timber beam, joist or rafter to provide a strong connection, to resist downward force and to provide structural stability. The galvanized coating would allow the hanger to be used outdoors. They can be fixed, where fixing is necessary, with either screws or nails.
How much weight can a 2×8 support?
A 2×8 will adequately support a dead load of 20 psf and a live load of 40 psf depending on some factors, including allowable span. This equates to a total load of 60 psf. Therefore, for a 2x8x10, the total load would equal 600 pounds per lineal foot.
