One of the most common problems i see with when people use a joist hanger the joist hanger is designed to have a withstanding force pushing down so the hanger needs to go all the way to the very bottom of the joist i see this all the time on decks we tear down on decks that are failing people don't seem to understand that these Metal Corner Brackets have to be all the way tight to the to your frame if they're not then you're not really serving the purpose i know that lumber can shrink that happened but when we are installing our joist hangers we always try to make sure they're super tight you'll notice that there's a couple of flanges right here one on each side those are like temporary supports that you can actually tack the joist hanger in place before you put the nails or screws in it so there's a couple different options how you can fasten this joist hanger i'm going to show you two different ways one is you nail it you can use tico nails they have to be rated for joist hangers you can't just use a regular 8d or 6d or any size nail you want it needs to be a special sized shank that's designed to withstand loads so we have ours loaded into a nail gun but these are two and a half inch nails a lot of people put inch and a half nails through these holes right here and then they put a two and a half to a three inch nail through the side.

But what we do we put two and a half-inch nails through here and then we use a two and a half-inch structural screw made by Simpson it's called an sd screw two and a half inches long and they're structural which means they're gonna be able to withstand an earthquake better than a standard screw would those go in through the side so you get a double shear holding power because you're going through the joist hanger you're going through the joist and then you're going into the ledger board these are approved to use with this hanger in this particular instance now these joist hangers come in a two by four two by six two by eight Outdoor Screws and two by ten sizing which is l us two four eight and 210 you can use a joist hanger on an as well it's engineered to be that way so they actually will sell you joist hangers for your joists in case you're running.

And you weren't sure they don't make a 212 z they used to but they don't anymore both plus 210z for your and your and then your you can actually use for 2x8 and but I prefer to go with a joist hanger if I’m running two by 10 joists that's just the way I am all right so we'll get to these in a minute but uh these again are stamped I don't know if you can see this but there's actually a stamp on every single screw with uh.
