The Simpson HUC612TF is a heavy-duty hybrid joist hanger that combines the structural benefits of both face-mount and top-mount connector designs into a single, code-compliant solution for 6x12 nominal lumber members. Engineered by Simpson Strong-Tie for end-of-wall and corner framing applications, this HUCTF-series hanger features two concealed top flanges that disappear flush into the assembly once installed, delivering a clean finished appearance without sacrificing load-bearing performance. Face-nailing keeps the hanger firmly anchored to the header member, and the 12-gauge steel construction with a G90 zinc galvanized coating provides the corrosion resistance required for demanding framing environments.

Key Features

• Hybrid face-mount and top-mount design - combines the installation flexibility of face-mount hangers with the concealed profile of top-mount hardware, giving framers a versatile connector suited to end-of-wall and corner conditions
• Two concealed top flanges - sit hidden within the framing assembly after installation, producing a flush, unobtrusive connection ideal for finished or visible timber framing
• Designed for 6x12 nominal joist members - provides a precisely sized seat and flange geometry for heavy timber and dimensional lumber framing without modification
• 12-gauge steel construction - delivers the structural rigidity required for heavy-duty, load-bearing residential and commercial framing assemblies
• G90 zinc galvanized coating - offers reliable corrosion resistance, extending the service life of the connection in moisture-exposed framing conditions
• Accepts up to 45 deg. of slope - allows the hanger to accommodate angled joist installations, adding versatility across a wider range of framing configurations
• Tested, load rated, and code compliant - HUCTF-series hangers meet established performance standards, supporting code-required documentation on permitted and inspected projects
• Face-nailing attachment method - allows secure anchoring to the header member using standard nails, simplifying the installation process for framers in the field

Why This Product

• One hanger, two installation advantages - the hybrid top-flange and face-mount engineering eliminates the need to choose between connector types, making this hanger a practical all-in-one solution for complex framing conditions including corners and end-of-wall applications
• Concealed flanges keep the finished assembly clean - unlike exposed-flange hangers, the hidden top flanges integrate into the framing without protruding hardware, a meaningful advantage wherever the structural connection will remain visible in the completed space
• Built-in slope capability up to 45 deg. - supports angled joist runs without requiring a separate specialty hanger, reducing hardware variety on job sites where roof pitches or architectural angles are part of the framing plan
• Tested and code-compliant performance - load-rated HUCTF-series construction means the connection can be documented and inspected with confidence, reducing friction during permitting and final inspection on both residential and commercial projects

Frequently Asked Questions

What size lumber is the HUC612TF designed to support?

The HUC612TF is designed for a nominal 6x12 joist or beam member. If you require a rough beam size, those are available by special order.

What nails are required to install the HUC612TF?

Installation requires (16) 0.162 in. x 3-1/2 in. nails in the header and (6) 0.162 in. x 3-1/2 in. nails in the joist.

Can the HUC612TF be installed at an angle, and does it support skewed installations?

The HUC612TF can be sloped a maximum of 45 deg.. However, no skew options are available for this hanger.

What material and coating is used on the HUC612TF, and is it suitable for corrosive environments?

The HUC612TF is made from 12-gauge steel with a G90 zinc galvanized coating, which provides corrosion resistance for demanding construction environments.
