The Simpson Double 2x10 Concealed Flange Joist Hanger Skewed Right ZMAX HSURC210-2Z is a 14-gauge steel structural connector engineered to support double 2x10 joist members at a 45 deg. right-hand skew in wood-framed floor and roof construction. Its concealed header flanges and ZMAX protective coating make it a reliable choice for both exposed framing conditions and environments where enhanced corrosion resistance is required - including applications involving treated lumber. The A2 acute flange turned-in design provides clearance at end-of-wall installations, and the hanger accommodates skew angles ranging from 40 deg. to 50 deg., offering practical flexibility across angled framing scenarios.

Key Features

• 14-gauge steel construction - delivers the structural strength needed for heavy double 2x10 joist connections in residential and light commercial wood framing.
• 45 deg. right-hand skew with 40 deg. to 50 deg. tolerance - accommodates real-world framing variation so installers are not locked into a single exact angle.
• Concealed header flanges - keep hardware out of sight in exposed framing applications, producing cleaner finished results without sacrificing structural integrity.
• ZMAX protective coating - provides enhanced corrosion resistance for use with treated lumber and in moisture-prone environments where standard coatings fall short.
• A2 acute flange turned-in design - creates clearance at end-of-wall installations, broadening the range of jobsite conditions where this hanger can be used.
• Square cut or bevel cut joist ends accepted - reduces field preparation requirements and saves installation time without compromising load performance.
• Made in the United States - reflects consistent manufacturing standards that structural professionals depend on for predictable performance.

Why This Product

• Purpose-built for skewed double-joist connections - rather than adapting a standard hanger with shimming or field modifications, this connector is specifically designed for 45 deg. right-hand skewed double 2x10 framing, eliminating guesswork and reducing installation errors.
• Corrosion resistance without compromise - the ZMAX coating is suited for treated lumber contact and demanding environments, meaning this hanger does not require an upgrade or substitution when project conditions call for higher corrosion protection.
• Cleaner results in visible framing - the concealed flange design keeps the connection profile low-profile and professional-looking, making it a smart choice where aesthetics matter as much as performance in exposed floor or roof assemblies.
• Built-in installation flexibility - acceptance of both square and bevel cut joist ends, combined with a 10 deg. skew tolerance range, means fewer fit issues in the field and more efficient installations across varied framing layouts.

Installation

Proper installation of the HSURC210-2Z requires the following fasteners:

• #9 x 2-1/2" Strong-Drive SD Connector Screws OR
• 0.162" x 3-1/2" Nails and 0.162" x 2-1/2" Nails

Fill all round and obround nail holes with the specified fasteners to achieve table loads. Where noted, triangle holes in the joist flange may be filled for additional uplift capacity. The joist end may be square cut or bevel cut. This hanger cannot be modified but will accommodate a 40 deg.- to 50 deg.-skewed joist.

Frequently Asked Questions

What joist size and skew angle is the HSURC210-2Z designed for?

This hanger is specifically designed to support double 2x10 joist members at a 45 deg. right-hand skew. It can also accommodate joists skewed between 40 deg. and 50 deg., providing some tolerance for field conditions where the angle is close but not exactly 45 deg..

Do I need web stiffeners when installing this joist hanger?

No. The HSURC210-2Z is designed to encapsulate the top flange of the joist, which eliminates the need for web stiffeners in standard installations, simplifying the installation process.

What material and coating is used on this joist hanger, and is it suitable for treated lumber?

The hanger is constructed from 14-gauge steel and features a ZMAX protective coating, which is a heavy-duty galvanized finish engineered for enhanced corrosion resistance. This makes it suitable for use with treated lumber and other demanding environments where moisture or chemical exposure is a concern.

What does the concealed flange design offer compared to a standard joist hanger?

The concealed header flanges on the HSURC210-2Z keep the fastening hardware hidden behind the header, resulting in cleaner visible lines. This makes it particularly well suited for exposed framing conditions where aesthetics matter. Additionally, the obround nail holes on the acute side allow nails to be installed parallel to the joist for faster and more accurate installation.
