The WP is a highly modifiable welded hanger designed to support joists on purlins or beams, with the ability to be skewed up to 84 and/or sloped to a maximum of 45. The BA is a cost-effective, top-flange hanger designed to carry medium loads with solid sawn lumber and higher loads with engineered wood products.
Jiffy Joist Hangers 150mm A quick and safe method of joist trimming for light, medium and heavy duty applications such as supporting floor joists, trimming stair wells and underslung joists. Short and standard legs have increased hole centres to spread load over greater area.

The THO25140 Top Mount I-Joist Hanger is engineered for I-Joist to header applications. It offers full lateral support of the I-Joist top chord, eliminating the need for web stiffeners in most applications. … The Seat Cleat will hold the I-Joist in place, eliminating spring back during nailing in the bottom flange.
Joist hangers are sized by joist depth, and run about 12 inch shorter than the nominal size of the joist (you can size deck joists by referring to Table R507. 6 in the 2018 IRC, which lists spans for deck joists sized from 2×6 to 2×12). For example, a 2×8 joist hanger is about 6 58 inches tall.
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.
According to Simpson, using their structural screws designed to work specifically with their joist hangers will result in a stronger connection than using standard nails. … You’ll need both the 1 screws and the 3 screws.
Joist Hangers, as the name suggests are designed to hold timber joists in place. They are used to anchor things like decking, floors and ceilings. Most joist hangers wrap around three sides of a wooden beam and nails or screws are put into the holes to keep it in place.

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.
But where they differ is in size and role. A beam is a large member made of very thick solid wood or laminated wood (or other materials), while joists are typically single boards that are often supported by beams running perpendicular to the joists. Beams and joists are used in all types of home structures.
A standard 210 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.
In a 2×6 joist I’d use a total of 8 8d or 10d nails, 4 per side, typically 8d in size or in some cases 10d – these are the most-commonly-used nail sizes when toe-nailing 2x framing lumber as unless you’re using box nails, larger nails tend to split the lumber, especially when, as in your photo, they’re nailed too close …
Post-installed holdowns have have allowable loads ranging from about 850 lb.up to nearly 20,000 lb.
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.

TOE-NAILING In contrast, toe-nailing produces a strong joint. The technique requires a pair of nails, driven at opposing 45-degree angles. It isn’t suitable for all joints, as the grain of one workpiece needs to be at an angle to the other.
Nails are often preferred for structural joining, including framing walls, because they are more flexible under pressure, whereas screws can snap. Nails are also called upon when securing plywood sheathing for exterior walls, installing hardwood floors, and attaching siding and roofing.
A: Joist hangers are safe, if they’re installed correctly. You typically need to hang a joist if the top of the joist needs to be on the same plane as the beam that supports it.
Types of Joist Hangers
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.
The Strong-Drive SD Connector screw is specifically designed to replace nails in certain Simpson Strong-Tie connectors and is the only screw approved for that application. The load-rated SD screw has been tested and approved for use in many popular Simpson Strong-Tie products.
