Can you use screws on joist hangers?
Outdoors use 16d double-dipped galvanized nails (or stainless steel when called for) for installing hangers. The manufacturers agree: Never use galvanized deck screws or drywall screws to install joist hangers. Those screws don’t have the shank size and toughness to support joist loads.
Can I use wood screws for joist hangers?
Although specialty screws are available for joist hangers, hanger manufacturers typically advise against using common deck screws for installing their products.
How do you hang joists without a hanger?
If you are not using joist hangers, then you should only be using nails to toe-nail your joist to your ledger board and rim joist.
Do joist hangers add strength?
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.

SD9 screws replace 8d and 10d common and 1-1/2″ size nails and 16d sinker nails (all nails 0.148″ and 0.131″ diameter) in face-mount hangers and straps. When using SD screws as double-shear fasteners, the 2 1/2″ SD screws are the correct length.
Do joists go on top of beams?

Can you use joist hangers for ceiling joists?
There is one place where a ceiling joist can truly “hang.” This is where it meets a beam on top of an interior or “partition” wall. A code-compliant connection includes the use of metal joist hangers, just like those used on outdoor decks.
How do you attach a ceiling joist to the wall?
Install each block between the center joists. Place one every 12 inches along the opening length and one at either end. End blocks should extend about 1 inch past the wall, unless there’s an adjacent wall, to allow sheathing and wall anchoring. Tap the blocks to get them in place; it will be a snug fit.
Can I screw into joists?
You can drill the holes anywhere along the length of the joist (first photo). If you have manufactured I-joists, you can drill holes up to 1-1/2 in. diameter almost anywhere in the web area (the area between the flanges). Just stay 6 in.
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 you use 2×6 joist hangers on 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.
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.
What size screws 2×8?
Use three 3″ screws for 2×6 headers, four for 2×8, etc. Like laying out walls and joists, use two 3″ screws for each 2×4 intersection. If two or more studs are parallel to each other, screw them together every 24″.
Are nails or screws stronger?
When deciding between nails and screws, keep in mind that nails are less brittle, so they provide greater shear strength. Screws, on the other hand, may not be as forgiving, but their threaded shafts hold better in wood and draw boards together much more tightly and they have greater tensile strength.
