The Simpson HSURC46 is a heavy-duty, 14-gauge concealed flange joist hanger engineered for 4x6 lumber members in wood construction. Skewed 45 deg. to the right, this U-shaped hanger is purpose-built to support framing members that meet at an angle, delivering structural integrity without sacrificing aesthetics. The concealed header flanges keep visible lines clean and unobtrusive in exposed conditions, making this hanger an ideal solution where appearance matters as much as performance. Finished with a Zinc Galvanized G90 coating, the HSURC46 offers reliable corrosion resistance suited for demanding construction environments.
Key Features
-
45 deg. Right-Hand Skew: Specifically designed to support 4x lumber members skewed 45 deg. to the right, with compatibility for joists skewed anywhere from 40 deg. to 50 deg.
-
Concealed Header Flanges: Heavy U-shaped design with concealed flanges provides cleaner visible lines in exposed framing conditions
-
A2 (Acute) Flange Turned In: The acute flange is turned inward to accommodate end-of-wall installation scenarios
-
No Web Stiffeners Required: Encapsulates the top flange of the joist, eliminating the need for web stiffeners in standard installation
-
Obround Nail Holes on Acute Side: Allows nails to be easily installed parallel to the joist for simplified fastening
-
Flexible Joist End Cuts: Accommodates both square-cut and bevel-cut joist ends
-
G90 Zinc Galvanized Coating: Provides corrosion resistance for long-term durability
-
Cannot Be Field-Modified: Engineered to precise tolerances; field modification is not permitted
-
Triangle Holes for Additional Uplift: Where noted, triangle holes in the joist flange may be filled for additional uplift capacity

Approved Applications
- Supporting 4x lumber members in wood construction framing
- Angled or skewed framing connections where a 45 deg. right-hand skew is required
- End-of-wall installations utilizing the turned-in A2 acute flange
- Exposed framing conditions where concealed header flanges provide cleaner visual lines
- Any application requiring a joist skewed between 40 deg. and 50 deg.
Installation
Fill all round and obround nail holes with the specified fasteners to achieve rated table loads. The following fasteners are required:
-
#9 x 2-1/2" Strong-Drive SD Connector Screws OR
- 0.162" x 3-1/2" Nails
The joist end may be square cut or bevel cut. Where noted, triangle holes in the joist flange may be filled for additional uplift capacity. This hanger cannot be modified but will accommodate a 40 deg.- to 50 deg.-skewed joist.
Frequently Asked Questions
- What is the difference between the HSURC46 and the HSULC46?
- The HSURC46 and HSULC46 are identical hangers except for their skew direction. The HSURC46 is skewed 45 deg. to the right, while the HSULC46 is skewed 45 deg. to the left. Both feature the same concealed flange design and are intended for 4x lumber in wood construction.
- What range of skew angles will the HSURC46 accommodate?
- Although designed as a 45 deg.-skewed hanger, the HSURC46 will accommodate joists skewed anywhere from 40 deg. to 50 deg., offering a degree of flexibility for framing layouts that fall slightly off the 45 deg. angle.
- Are web stiffeners required when using the HSURC46?
- No. Because the HSURC46 encapsulates the top flange of the joist, web stiffeners are not required for standard installation.
- Can the HSURC46 be field-modified to fit a different application?
- No. The HSURC46 is a pre-engineered connector with a fixed 45-degree right skew and should not be field-modified. Any alteration to the connector may affect its structural performance and void load ratings. Consult Simpson Strong-Tie for alternative configurations.
