The Simpson HU410SS is a heavy-duty, face-mount joist hanger engineered specifically for 4x10 nominal lumber and constructed from 14-gauge stainless steel for exceptional corrosion resistance. Part of the trusted HU series from Simpson, this connector is designed for structures requiring additional strength and safety factors, making it the preferred choice of engineers and contractors who need a hanger that is rigorously tested, load rated, and code compliant. The stainless-steel finish provides superior protection against moisture and chemical exposure, making it particularly well-suited for exterior framing and assemblies that incorporate pressure-treated or chemically treated lumber.

Key Features

• 14-gauge stainless-steel construction - delivers a heavy-duty connection with the corrosion resistance needed for demanding exterior and treated-wood applications where lighter or standard-finish hangers may degrade over time.
• Stainless-steel finish - provides extra protection against moisture, chemicals, and the corrosive compounds found in treated lumber, extending the service life of the connection in harsh environments.
• Precision fit for 4x10 nominal lumber - engineered to match the exact joist size, ensuring a secure, accurate face-mount connection without guesswork or field modification.
• Extra optional triangle holes - give installers the flexibility to add fasteners for increased load capacity when project conditions demand a higher-strength connection.
• Tested, load rated, and code compliant - the HU series meets building code requirements and comes with verified load ratings, giving contractors and inspectors confidence on residential and commercial job sites alike.

Why This Product

• Built for corrosive environments - the stainless-steel material goes beyond standard galvanized protection, making this hanger a reliable long-term solution for exterior structures, coastal framing, and connections involving chemically treated wood.
• Engineered for strength and safety - designed specifically for applications requiring additional structural capacity, the HU series is tested and load rated so builders can match the right connector to the actual demands of the project.
• Code-compliant confidence - HU-series hangers are manufactured to meet building code standards, reducing the risk of failed inspections and giving engineers, contractors, and homeowners verified performance they can document.
• Flexible installation with optional triangle holes - the extra fastener holes allow the connection strength to be increased when needed, offering adaptability across a range of structural framing scenarios without switching to a different product.

Frequently Asked Questions

What lumber size is the HU410SS designed to fit?

The HU410SS is precision-engineered to fit 4x10 nominal dimensional lumber, providing a secure and accurate face-mount connection for that specific joist size.

Why choose stainless steel over a standard galvanized hanger?

Stainless steel offers superior corrosion resistance compared to standard finishes, making the HU410SS ideally suited for exterior applications and projects involving treated wood, where standard galvanized connectors may fall short.

What are the optional triangle holes on the HU410SS used for?

The extra optional triangle holes provide flexibility for additional load capacity when project requirements demand it, allowing you to increase the connector's performance beyond its standard nailing pattern.

Is the HU410SS tested and code compliant?

Yes. HU-series hangers are tested, load rated, and code compliant, making them a trusted choice for engineers and contractors working on structures that require additional strength and safety factors.
