The Simpson HUC612SS is a heavy-duty, stainless steel, face-mount concealed-flange joist hanger engineered for structures that demand additional strength and elevated safety factors. Sized for nominal 6x12 lumber, this hanger features a 5-1/2 in. seat width and concealed header flanges that deliver cleaner, more refined visible lines in exposed framing conditions - making it equally at home in architecturally finished spaces as it is in demanding structural applications. Formed from 14-gauge stainless steel, the HUC612SS provides superior corrosion resistance for exterior environments and installations involving treated lumber. As part of the tested and load-rated HUC series, this hanger is code compliant and engineered to give builders and engineers the confidence of a proven, certified connection.

Key Features
