The Simpson HU48SS HU Stainless-Steel Face-Mount Joist Hanger for 4x8 is a heavy-duty structural connector engineered by Simpson to deliver reliable load transfer and long-term durability in demanding construction environments. Fabricated from 14-gauge stainless steel, this face-mount hanger is purpose-built for exterior framing and treated-wood applications where corrosion resistance is critical. As part of the HU series, it is tested, load rated, and code compliant - making it a dependable choice for engineers and contractors tackling residential and commercial structural projects alike.

Key Features

• Extra optional triangle holes for additional load - gives installers flexibility to increase fastener count and maximize load capacity when project conditions demand it
• Tested, load rated, and code compliant - meets building code requirements out of the box, reducing approval friction and giving you confidence in structural integrity
• Designed for nominal 4x8 lumber with a 3-9/16 in. seat width - ensures a precise, secure fit for the intended joist size without modification or guesswork
• 14-gauge stainless-steel construction - provides the heavy-duty strength of a thick-gauge connector combined with the corrosion resistance needed for wet, exterior, and treated-wood environments
• Stainless steel finish offers extra corrosion resistance for exterior and treated-wood applications - outperforms standard finishes over time where moisture and chemical exposure would otherwise accelerate deterioration

Why This Product

• Built for harsh conditions - stainless steel construction makes this hanger a smart investment for decks, docks, pergolas, and any structure where treated lumber or outdoor exposure would quickly compromise a standard galvanized connector
• Heavy-duty capacity with design flexibility - the optional triangle holes let you add fasteners beyond the standard pattern, giving you a straightforward path to higher load ratings without swapping to a different hanger
• Code-ready right out of the box - HU-series hangers are tested and load rated, so inspectors and structural engineers already recognize and trust them, helping keep your project on schedule
• Simpson engineering you can rely on - Simpson connectors are the preferred choice of contractors and engineers for a reason: consistent manufacturing quality and rigorous performance testing back every piece

Frequently Asked Questions

What size joist is the HU48SS designed to support?

The HU48SS is designed for a nominal 4x8 member size, with a seat width of 3-9/16 inches to accommodate that joist dimension.

Why should I use stainless steel joist hangers instead of standard galvanized hangers?

Stainless steel offers extra corrosion resistance, making the HU48SS especially suitable for exterior applications and projects involving treated wood, where standard finishes may degrade more quickly over time.

What fasteners are required to install the HU48SS?

Install with (10 - 14) 0.162-in. x 3-1/2-in. stainless-steel ring-shank nails in the header and (4 - 6) 0.148-in. x 3-in. stainless-steel ring-shank nails in the joist.

Are HU-series hangers code compliant?

Yes. HU-series hangers are tested, load rated and code compliant, making them a reliable choice for both residential and commercial structural applications.
