The Simpson APHH46R Outdoor Accents Heavy Joist Hanger is a concealed-flange connector built to join rough 4x6 beams to girders in custom outdoor living structures. Part of the Simpson Outdoor Accents decorative hardware line, it brings together structural performance and a refined, finished appearance - making it a natural fit for decks, pergolas, and other exterior framing projects where visible hardware needs to look as good as it works. The ZMAX galvanized finish with black powder coat gives this heavy hanger the corrosion resistance required for exterior and treated-wood applications, while the straight-edged concealed-flange profile keeps connections looking clean and intentional.

Key Features

• Concealed-flange design with straight edges - eliminates the exposed, splayed look of standard hangers so joist connections appear clean and finished in visible outdoor structures
• Sized for rough-cut 4x6 lumber - fits an actual 4x6 member precisely, ensuring a snug, structurally sound connection without gaps or shimming
• 12-gauge steel construction - delivers the load capacity needed for heavy beam connections in demanding outdoor framing applications
• ZMAX galvanization with black powder coat - provides a dual layer of corrosion protection suited for exterior environments and contact with pressure-treated lumber
• Complements the Outdoor Accents Mission Collection and Avant Collection - coordinates with other decorative connectors and fasteners in the line for a cohesive, design-forward look across the entire structure

Why This Product

• Strength and aesthetics in one connector - unlike standard joist hangers that prioritize function alone, the concealed-flange design gives outdoor living structures a polished, architectural look without sacrificing the heavy-duty performance the framing requires
• Purpose-built for rough-cut timber framing - the APHH46R is specifically engineered for actual rough 4x6 lumber, so builders working with rough-sawn timbers get a precise, secure fit rather than an oversized or improvised solution
• Corrosion resistance designed for the outdoors - the combination of ZMAX galvanization and black powder coat addresses the two main threats to exterior hardware: moisture and chemical exposure from treated wood, helping the connection hold up season after season
• Part of a coordinated decorative hardware system - because it pairs with other Outdoor Accents connectors and installs using the specified Outdoor Accents structural screws and hex-head washers, it fits naturally into a complete, matched hardware plan for decks, shade structures, and similar outdoor builds

Frequently Asked Questions

Is this hanger designed for rough-cut or nominal lumber?

This connector is designed for rough-cut lumber, not nominal lumber (the most common type). It is specifically sized to fit a joist that measures an actual 4x6 inches. If you have a nominal joist measuring 3-1/2 x 5-1/2 inches, you will need the APHH46 instead.

What fasteners are required to install the APHH46R?

Install with Outdoor Accents Structural Wood screws: (2) SDWS22312DBB and (6) SDS25300, and (2) STN22 hex-head washers (sold separately). Use the SDWS22312DBB structural wood screw and STN22 hex-head washer to connect to the joist, and the SDS25300 Strong-Drive SDS Heavy-Duty Connector screw to connect to the header.

Why does the APHH46R have a concealed-flange design?

The concealed-flange design features straight edges that provide a cleaner looking installation for joist connections, making it ideal for visible outdoor living structures where both appearance and performance matter.

Is the APHH46R suitable for exterior and treated-wood applications?

Yes. The APHH46R features ZMAX galvanization with a black powder coat, which offers extra corrosion resistance for exterior and treated-wood applications, making it well-suited for outdoor structures exposed to the elements.
